Can someone please elaborate on how (and how much) value attending this event adds? Is it geared more for helping you apply to YC, answer generic startup related questions etc?

Specifically, I am selected in YC Startup school and will have to spend at least a day to travel to attend the session. Is it worth the extra time and money?


I've gone to office hours and I thought it was very useful, although I'd imagine it would vary very widely based on who you actually end up talking to, how much experience/insight they have into your sector/product/(even better) the specific problems you're having, as well as how interested they are in what you're doing.

The people from YC (at least the few I've met) spend a crazy amount of time around startups and have a lot of insight into all kinds of random problems that startups have that they see from being so deep in the startup world, so if you can talk to one of the people from there who's in your general area, and you have specific issues that you're grappling with how to approach and how to avoid pitfalls, they might be able to add a lot of value pretty quickly based on having seen people go through similar kinds of problems.

If you just want to go to the general Q&A, already are around hackernews and are already in startup school, I'm not sure it would necessarily be worth a whole day of travel. The Q&A is necessarily pretty general, and you probably are already getting a good general footing from startup school, although I second the other guy's exception of if you're really good at networking, since there will be interesting people there.


Went to a similar event at Harvard some years ago. Was interesting but if you are a HN regular you probably get as much out of blog posts following happenings online as at the event.

YMMV if you are a better net-worker than I am.


> get as much out of blog posts following happenings

Curious, what are some of the best blog posts/sites to follow?


I was at the Stockholm evening two (?) years ago when they visited the company I worked for then, Wheelys Café. It was certainly an interesting evening and a fun event, but I would not have travelled a day to attend.


Just curious, when online, I would expect Google Speech to text models to outperform most of the offline only models. I also believe for text to speech their wavenet models are one of the best available for developers?

If you're looking into developing something, if I were you, I would look at three things.

1.) Form factor - it's amazing how much of this industry relies on either hearing aids or holding a mic/phone in someone's face.

2.) Quality of voice - I'm lucky. I am not "deaf", I just have trouble picking out voices at certain frequencies, or all voices if there's enough noise. Luckily, I don't have to speak with an electronic voice. If I did, I'd want a voice that sounds a little human and has some inflection. This is a tough problem, but if you can solve it, the Kurzweils of the world would be playing catch up.

3.) Targeting - I damaged my hearing when I was young, addicted to very very loud music (especially live) and not particularly bright. I'm in my forties and still not particularly comfortable using assistive technology. If I were a teen, I'd be fucking mortified to use any of these. Fuck, I could have easily failed high school because of that. I can't escape the feeling that there's a market for people like me. I would love an audiologist's office with tattoos and Bad Religion. If that feeling came to an assistive device, I'd be a customer.

Of course, I'm a weirdo and it's not always the best idea to start a company to cater to a weirdo!! :)


Thanks a lot, this list is really helpful!


> It is worth recalling that SpaceX only flew a "used" booster for the first time in March 2017.

It's amazing this happened just a little over a year ago.


It was a epoch defining change. It does feel like a ton of time ago, and everyone in the industry (most notably ULA, Arianespace and the Chinese) are trying to figure out what they do now that the SpaceX steamroller is in full force.


Indeed. Could be that having a legacy rocket programme is if anything a hindrance in this new world of reusability - Ariane in particular seems to be in danger of becoming mainly an employment scheme that builds rockets on the side. For fairness I guess I should say SLS isn't looking too clever at this point either.


You're missing the point of Ariane. Its purpose is providing independent access to space for ESA member nations at a reasonable price, and as insurance against a launch monopoly (it upper-bounds what others can charge ESA). Ariane 5 is also extremely reliable, which is very important for some launches (NASA's James Webb telescope is going to launch on Ariane 5, for example). Ariane's goal is not to win the most commercial contracts or compete with SpaceX on price.

This is also the reason reusability doesn't make sense for Ariane. With less than ten launches per year, fixed costs make up a large portion of the cost. If they only needed one rocket per year, it wouldn't really get all that much cheaper because they still need the factory.


And yet:

'SpaceX is so cheap that Ariane's CEO worries SpaceX could eventually "kick Europe out of space" if Ariane cannot figure out a way to launch its rockets more cheaply'

https://www.fool.com/investing/2018/06/02/europe-complains-s...


> Ariane 5 is also extremely reliable

It certainly is reliable, but it's not extremely reliable. It's had 2 total failures and 3 partial failures out of 99 launch attempts, including a partial failure this year on SES-14 that left the satellite in-orbit, but inclined 20 degrees to the equator, which will significantly shorten the satellite's lifespan.


Insurance against a launch monopoly would be more effected by competition in general, no need to build your own rocket. I have also never heard anybody from ESA make that claim.

Ariane 5 is reliable but the primary reason it is launching rather then ULA is not reliability but politics.

> Ariane's goal is not to win the most commercial contracts or compete with SpaceX on price.

That is false. That was exactly what their goal was all the way up to a 1-2 years ago when they finally realized how badly they fucked up.

They spent the last 10 years laughing at SpaceX and telling everybody how stupid SpaceX is and how nothing is gone work and how much better they are.

> This is also the reason reusability doesn't make sense for Ariane. With less than ten launches per year, fixed costs make up a large portion of the cost. If they only needed one rocket per year, it wouldn't really get all that much cheaper because they still need the factory.

You are repeating what is essentially propaganda that ignores important facts.

The reason Ariane can only launch 10 times a year is because they totally failed in innovating and rested their success for a long time and now that they got 3 billion to develop a new rocket, that they claimed would be competitive. However the totally fucked that up and are not even close to being competitive.

The very reason they go all this money for Ariane 6 was to build something competitive so they could continue to capture commercial launch so that government flights were cheap.

So it is not that re-usability is not worth it, its that they failed to make a commercially viable product and without that they are just monopolistic launch with a low launch rate.


> Its purpose is providing independent access to space for ESA member nations at a reasonable price

> Ariane's goal is not to win the most commercial contracts or compete with SpaceX on price

Winning commercial contracts is how the price is kept reasonable. As you pointed out fixed costs are very large and launching GTO satellites helps spread them around.

If SpaceX kicks Ariane out of the commercial market then ESA governments will have to pay more for their own launches.


Its purpose is providing independent access to space for ESA member nations at a reasonable price

What if the "reasonable price" changes?


It's purpose has always been to be a globally competitive commercial launch provider. A purpose they excelled at for decades. While it's purpose is now shrinking to being Europe's government launcher it should be noted that this is an event that is happening, not merely a continuation of the status quo.


What happens with the JWT if the rocket blows up on launch? How long(and how much $$$) would it take to build another one, having already built one?

Is this an instance where the government should follow the maxim from Contact: "Why build one, when you can build two for twice the cost?"


> Is this an instance where the government should follow the maxim from Contact: "Why build one, when you can build two for twice the cost?"

The maxim in Contact was different - "Why build one, when you can build two, but keep the second one secret", right?

I do hope JWT could be recreated cheaper than costs to create it in the first place. No matter though, we'll still need other space telescopes anyway, so both reliability and price to orbit are important.


One of the main goals of the Ariane rocket system is also provide jobs,not efficient Lunch system. If they create a reusable lunch system what the workforce will do then?


Given Ariane's French roots I think we can count on the lunch and all other meals being not just efficient, but superbe!


That is false. Historically this was not the reason, this is now the new claim they make but it was never the specific intent.


Build space stations and moon bases?


I don’t think SLS ever looked good, except when evaluating it for pork value.


Here is what I would like to ask the head of NASA if I had the chance to interview him.

First I would ask him to list the various specific missions that the SLS is designed to carry out.

And then I would ask if the BRF lives up to its promises, which of those missions, if any it would not be able to carry out.


If he were able to be completely honest, I imagine his answers would be “satisfy members of Congress by sending money to their districts.” SLS exists by Congressional mandate, and I don’t think NASA actually wants it.


> It was a epoch defining change

Not yet. Costs haven't fallen. The epoch-defining change would be back-to-back commercial launches with the same booster in a short period of time with zero or little retrofitting.


> Costs haven't fallen.

I disagree. I highly doubt reusing a booster has been more expensive to SpaceX than building new boosters. It is also speculated that at least the first few customers of reused boosters were given a discount.

If you are saying customer cost has not fallen, you may be correct. I would counter with the fact that SpaceX is already a low cost provider, lowering their price more may not increase their overall profits.

> The epoch-defining change would be back-to-back commercial launches with the same booster in a short period of time with zero or little retrofitting.

The booster SpaceX plans to reuse today is a "block 5" booster. This is basically the design that SpaceX hopes will enable that zero or little retrofitting reuse.


> I highly doubt reusing a booster has been more expensive to SpaceX than building new boosters

Well, they are. Which is natural, because the program is still R&D more than mass production.

> This is basically the design that SpaceX hopes will enable that zero or little retrofitting reuse

When that rapid re-use is demonstrated, it will mark the epoch. We could retcon to the original re-use, or even booster recovery. But that's premature.

(I'm still super excited about everything SpaceX does.)


Costs have already fallen. Iridium paid far less to launch their next generation fleet despite it being the same number of satellites, each of which are individually quite heavier than the previous generation (meaning, they purchased much greater launch capability but at a strictly lower cost). And several customers have taken advantage of the extreme low costs of reused launchers. Sure, right now it's only maybe $10 million cheaper, but $10 million is still $10 million, and for some that makes the difference between feasibility and infeasability.


If this current revival of spacecraft innovation goes on to create rapid, fully reusable spacecraft(BFR, New Glen, etc.), I think the epoch changing moment will be seen as the first landing of the first stage Falcon 9 on December 21, 2015. Similar to the first flight at Kitty Hawk. But if we fail to take to the stars, it will soon be forgotten and only remembered as a nostalgic touchstone for a few dreamers. Sort of like how I imagine how people will think of the first moon landing if, in a thousand years, humans have still not made it back.


> Not yet. Costs haven't fallen.

That is false. You already pay 10 million less. That is 15% of the launch price. And 15% of the extremely cheap price that SpaceX was already selling.

The reality is that SpaceX simply increased its margin. The technology is still epoch defining.

If any competitor comes even close to SpaceX in price, they will simply drop the price again.


Don't forget Roscosmos, who is going to be in a world of hurt when NASA and other customers stop using their services and instead use SpaceX.

https://arstechnica.com/science/2018/06/russia-may-lack-the-... sums it up nicely.


>It was a epoch defining change. It does feel like a ton of time ago, and everyone in the industry (most notably ULA, Arianespace and the Chinese) are trying to figure out what they do now that the SpaceX steamroller is in full force.

Nitpicking on the language: why would SpaceX be a steamroller? Steamrollers are slow. Also, what does it mean for a steamroller to be in full force? Steamrollers push downward at a constant force, don't they?

I understand that SpaceX is crushing its competition, so you want to bring the steamroller metaphor, but perhaps for what you are saying other metaphors would be a better fit.

Further reading: Orwell, Politics and the English language[1]

[1]https://ebooks.adelaide.edu.au/o/orwell/george/o79p/


It’s an idiom.


It is not clear what "it" you refer to here.

Referring to SpaceX as a steamroller is a metaphor[1].

"In full force" is, indeed, an idiom that generally means "in entirety", "completely"[2]

"Steamroller in full force" is neither a metaphor nor an idiom. It's a mashup of the two, and a phrase hitherto unuttered because it doesn't carry meaning.

Put simply, the set of things that can be "in full force" generally does not include steamrollers.

Please see Orwell's essay I linked to. "Fascist octopus has sung its swan song" is an example there that is a similar mix of metaphors.

There are many ways this can be fixed; steamrollers can gain momentum, for example.

As I said - it's not a principal point; I'm nitpicking. However, I believe clear communication is important - so here is an opportunity to improve.

Have actual cost saving numbers been published? I remember reading estimates back in 2016 or so of ~60% but I'd be interested in what the real numbers were


Gwynne Shotwell once noted that even the very first refurbished booster cost less than 50 % of a new one to refurbish. They've learned a lot since then and Block V is designed to do at least 10 launches I think without refurbishment (this one has been taken apart, though, since it's the very first one that launched).


IMHO this is how self driving applications should start. Driving on the US freeways (say between LA and SF) isn't about your driving skills. It's mostly just about trying not to fall asleep. And machines are way better than humans at this!

Even outside the US, there are many areas (like UAE), which have amazing highways, sparse traffic and there isn't rail/air connectivity to some places. Self driving "shuttles" seem perfect for those applications.


In general, highways seem like a pretty logical starting point. There are some potential complications like car accidents and debris but they seem far more tractable than random pedestrians, cyclists, and all the complex driving behavior on city streets resulting from traffic lights, trucks stopped to make deliveries, etc. etc.

It doesn't enable end-to-end autonomous taxis, so you need a sober, licensed driver in the driver's seat even if they don't need to be able to take over on a second's notice.

Handling long distance highway driving would actually be a big win. It just doesn't stir imaginations the same way that completely eliminating a driver door-to-door does--especially among people who really want to get out of car ownership and driving entirely.


> especially among people who really want to get out of car ownership

I have brought this up before and I still do not understand how or why this idea is so tightly coupled to fully autonomous vehicles. I don't see how removing a human driver from a car service is going to change the dynamics enough to drive legions of people who own cars to get rid of them if they haven't done so already. The only friction a human driver adds right now is cost, but I don't see the cost savings of removing the driver being high enough to move the needle.


There seems to be an implicit assumption that autonomous driving would somehow make the cost of effectively renting cars by the mile (and have them come to your door) almost too cheap to meter. Whereas, especially for transportation options that involve multiple people in a vehicle, the cost of a driver isn't really all that much relative to the overall cost of operating a vehicle.

For any imagined scenario involving autonomous vehicles ushering in new modes of sharing, renting, etc., a useful question to ask is: "Why don't we have this today?" And, if the answer is anything other than "$10/hour for a human driver makes it too costly," then you should probably reconsider.


> Whereas, especially for transportation options that involve multiple people in a vehicle, the cost of a driver isn't really all that much relative to the overall cost of operating a vehicle.

Do you have a source on this? It’s my understanding that most mass transit systems in the US spend a huge amount on operator compensation. BART, the one I’m most familiar with, spends $500m of its $691m operating budget on salary and benefits [0] despite the fact that BART trains already drive themselves!

[0]: https://www.bart.gov/sites/default/files/docs/FY18_Budget_Su...


First off, you cannot ignore the $876mm capital portion of the budget; that money needs to come from somewhere.

Second, that $500mm covers every employee of BART. The administrators, maintenance personnel, police, and other non-operator functions do not go away. Without knowing what portion of that line item goes to operators one cannot make a judgement on how much cheaper the system would be without them.


Of course you're right; my comment was mostly tongue-in-cheek. Actual train operator salaries probably cost BART about $50m annually, not $500m. In both the cases of BART and private cars, the money to pay for tracks or roads comes from taxpayers. The trains themselves are now 40+ years old, and are finally being replaced at a cost of ~$300m this year. Grandparent post specifically talked about operating costs though.

All that said, trains are basically the most efficient mode of transport from a (number of drivers) / (number of passengers) perspective.

But speaking seriously for a moment:

- Lyft charges riders about $2/mile in the Bay Area [0] before fees.

- The IRS lets you depreciate your vehicle at a rate of $0.545/mile.

- A reasonably efficient car burns ~40 mpg on freeway, at $3.50/gallon that's ~$0.09/mile.

So, of the $2/mile the riders pay, about 1/3 of that is costs associated with purchasing and operating the vehicle (according to IRS estimates) and fuel.

If we eliminate the rest via autonomous driving, and taxis became 65% cheaper, I suspect many people would make much more use of them.

[0]: https://www.lyft.com/pricing/SFO


Utilization rates are 50-58% for Uber or Lyft. When you take it into account that a taxi is not en route 100% of the time, and add the cost (interest, depreciation) of a much more expensive vehicle, I think your 65% savings go up in smoke.


Sorry, I'm not smart enough for this comment to stick with me. Could you walk me through how 50% utilization means the savings go up in smoke?

The most compelling thing I can pull from your comment is "autonomous cars will be 3x as expensive as regular cars (at least), so you won't save anything". That may be short-term true, but is almost certainly long-term false.

A 50% utilization compared with 100% utilization makes almost no difference in vehicle cost structure -- if anything, it actually increases the labor fraction of taxi cost.

If you're driving your car 50% of the time, then wear and milage is the dominant depreciation factor (rather than age). But a human sitting around doing nothing but waiting for that 50% of the time doubles the labor (time) cost of the service, suggesting an even greater savings from eliminating the human driver.

What am I missing?


I was assuming humans and self-driving cars both get revenue from riders, but don't get paid in between. And I'm interpreting utilization as the percentage of the time that riders are paying.


The human's time has a cost, and even if the rider doesn't explicitly pay it, it is factored in to the labor cost of the driver.

The machine's time cost is time-based depreciation, which is pretty low.


How much of the Labor & Wages go to drivers rather than maintenance, security, etc.? The latter are needed even if you don't have drivers.

I couldn't find a breakdown in the paper.


For renting cars there is a big advantage. You may notice that different drop offs have different fees associated. This is because people tend to collect around certain areas. This creates the need for company drivers to redistribute the cars. Being able to do that dynamically and automatically has a huge advantage. It also allows you to make the rental locations more sparse and efficiently packed.

So yes, it does lessen the cost of renting cars. But it doesn't make it anywhere near too cheap to meter.


The more "mass" the transit the harder it is for the vehicle to go exactly where all the people on it want to go. Subway, maybe walk a 1/2 mile, bus somewhat less but lots of stops, individual road transport, very close.

An auto-car just sitting costs almost nothing per hour (capital cost, but very little other cost), so you can have lots of them everywhere. Pickup time can be very short. I almost never used taxis in my town because of long and unreliable pickup times. Use uber all the time now. I still own a car, but if I did not have off street parking like many in my neighborhood, getting rid of it would be a no-brainer.


> An auto-car just sitting costs almost nothing per hour (capital cost, but very little other cost)

I'm not sure it's fair to dismiss capital cost parenthetically as part of "almost nothing". Maybe if the auto-cars were retrofitted 10-15 year old vehicles and the retrofitting cost a fraction of the vehicle's value, I'd agree. However, if they're all brand new (and even electric, where the TCO is weighted toward capital and away from operating costs), I say it's far from almost nothing.

Additionally, you go on to point out:

> if I did not have off street parking like many in my neighborhood, getting rid of it would be a no-brainer.

Therein lies a cost of "just sitting" that is routinely brought up in any car vs public transit (or other alternatives like bicycles or walkable designs) conversation.

The denser the area, the higher the cost. I suspect that if you did not have off street parking due to density, the parking portion of the "just sitting there" cost included in the pricing of the auto-car would make it no longer a no-brainer.

Where auto-cars could at least gain some space efficiency is in being able to park bumper-to-bumper and with minimum side clearance, since there would be no need for a human to enter or exit while it's in storage.


Auto cars can also drive away from expensive parking when not in use. Lots of Uber drivers live in Sacramento but work in SF 80 miles away.

Maybe if interest rates go up capital costs will be an issue, but using a 100k car paying 4% interest is $4000 a year or about $0.50 per hour. When not moving there is basically no wear and tear or fuel costs. Almost nothing compared to paying a driver.


> Auto cars can also drive away from expensive parking when not in use.

Driving away is, of course, not standing still. That increases the cost, but, perhaps more importantly, increased latency (or, rather, jitter).

They need not be stored in the most expensive, densest areas, but, for those who want to get rid of car ownership, that non-zero cost (especially if borne by the public with free on-street parking) isn't likely one they're willing to ignore.

> about $0.50 per hour.

A car sitting idle for 9 hours per day and averages 30mph while driving adds 1 cent per mile. A car sitting idle for 18 hours adds 5 cents per mile.

The former may be almost nothing, but the latter isn't.

> Almost nothing compared to paying a driver.

I still disagree, but that's just semantics.


Depreciation and utilization rates need to be incorporated.

If interest + depreciation is about $9K/yr, that's $25 a day, which means if you drive 8 hrs a day and have a 58% utilization rate, is $5.38/hr which is not all that far from what Uber drivers net. At 30 mph, it's 18 cents added per mile.

A self-driving car could perhaps operate more than 8 hours a day, but that doesn't mean that customers will be equally available at all hours.

I strongly suspect that when you do a proper analysis, self-driving cars are just competitive and not hugely cheaper.


> Depreciation and utilization rates need to be incorporated.

That's tough to do, since we don't know either one. I suspect there's also a (perhaps incorrect) assumption that an unused auto-car will be "just sitting there" rather than moving, in which case utilization is, effectively, 100%.

That's not possible with a human driver in at least the case of a long one-way trip. However, with auto-cars, this could end up merely increasing the capital cost at the expense of unpaid/empty trip cost.

The extra cost is something I mentioned in my latency/jitter comment, wrt cheaper parking.

> $5.38/hr which is not all that far from what Uber drivers net

I didn't check your arithmetic, but, if so, it's is quite far from the fair/livable wage of $15/hr that at least I've been assuming for this conversation.

The fact that rideshare services are currently, effectively, paying much less is certainly an indication that even that may not be enough to lure people away from ownership.


Utilization rate means percentage of time that is billed to a customer, I believe/presume. Whether a car is moving is not the same thing. The issue is whether it is on the clock or not, and given that computers already are used to match passengers and route cars, I'm not clear on why we would expect a drastic increase. Currently, we see 50-60%. Even a perfect routing algorithm can't make it 100%, because there are only so many customers, so things like how many cars there are per customer matter. If you reduce the cars per customer, service suffers. If you increase the number, utilization falls.


> given that computers already are used to match passengers and route cars, I'm not clear on why we would expect a drastic increase

It depends on what the denominator is.

If it's only the time between when a driver/auto-car "accepts" the ride and the end of the ride, there's little reason [1] to expect a drastic increase.

However, if the denominator is the total time the driver is "on duty", which is, I believe, what is generally used to calculate rideshare drivers' effective hourly compensation, then my original point stands. That is, an auto-car can be "on duty" even while just sitting in storage.

The current algorithm also doesn't tell rideshare drivers where to be while on duty, only routing them once a ride is requested. In the auto-car scenario, the computer has complete control, so a predictive algorithm could increase utilization, even if the denominator is time-in-motion.

Whether any increase would be drastic is debatable, but there's opportunity for something.

[1] Currently, the computer routing algorithm has an incentive to optimize for time at the expense of distance (since it's the driver who bears the expense of the unbilled distance, AFAIK). In the case of an auto-car, that perverse incentive would be absent, but I don't expect the difference to be huge.


"That is, an auto-car can be "on duty" even while just sitting in storage."

If you consider the robot to "work" for more hours than a human, that's great, but due to the lower average revenue, it needs to be cheaper in order to be competitive with humans. There's no way to move your self-driving car to the opposite side of the world for the night.

"Whether any increase would be drastic is debatable, but there's opportunity for something."

If self-driving cars are cheaper, it seems like that would lead to more of them driving longer hours than humans, which would lower the utilization rather than increase it.


> due to the lower average revenue, it needs to be cheaper

It's unclear to me, but this may be tautological, or at least reversible (by being cheaper to be competitive, it reduces revenue). Perhaps I'm missing your point?

> There's no way to move your self-driving car to the opposite side of the world for the night.

Ah, but that's moot. Unlike with a human driver, an auto-car doesn't need to be moved to the opposite side of the world (or an approximation, like Sacramento from SF) for the night.

> If self-driving cars are cheaper, it seems like that would lead to more of them driving longer hours than humans, which would lower the utilization rather than increase it.

You're still confusing "driving" (in motion) with "on duty".

Also, even if an auto-car is cheaper while driving, that doesn't matter if the different parties are bearing the cost of off-meter driving. In the auto-car case, it's the vendor (e.g. Uber), so there's a strong incentive to maximize utilization. In the human case, it's the driver, so the vendor has no such incentive (nor even the ability during "on duty" but not driving-for-that-vendor times).


Seems like depreciation (assuming straight line over 20 years) is going to roughly double that figure.


Nice inclusive term, individual road transport can only mean bicycle since that is the only way you can get enough parking close for everyone.


auto-vehicle? I'll try to use that. A much better word especially since car=always bad for some people.

Bicycle parking is also a problem in many areas that have a high density of bicycle users. See Amsterdam train stations or apartment buildings where you have to store your bike in your 600sqft apartment.

Walking is really the best although these new electric skateboards seems to be almost totally portable and storable.


If the technology becomes commoditized, the cost reduction would be massive. A $30000 vehicle can drive 200K miles for the price of fuel and occasional cleaning. That's in the 30 - 50 cent/mile area, almost a full order of magnitude. Insurance premiums will depend on how safe they are - so they will be very low if self driving cars are to be allowed in any way on the road.


> A $30000 vehicle can drive 200K miles for the price of fuel and occasional cleaning.

That is significantly underestimating the operating costs of a vehicle, especially a vehicle that is used heavily. There is a lot of periodic maintenance required, and the frequency increases as usage gets more stressful. Then there is non-periodic maintenance, be it from accidents, vandalism, or just flawed parts.

It's true that most of these costs come in even if you own, but putting 200k miles on a car over eight years costs less (both per-mile and per-unit-time) than putting 200k on in two years.


> putting 200k miles on a car over eight years costs less (both per-mile and per-unit-time) than putting 200k on in two years

The per mile part sounds like a personal speculation. (Per unit of time is obvious and irrelevant here)

Quite the contrary, it's most efficient to put the load in a short span to minimize time-limited consumables like belts and seals, fixed costs like insurance and regulatory charges per vehicle, interest, depreciation of things like paint and esthetic appeal etc. The battery has an age induced wear also, the tech is moving fast and more efficient vehicles are always appearing and so on.


The IRS allows a 50 something cents per mile business expense deduction. And if you run some numbers that’s a pretty good ballpark for the cost of operating a car.


Considering they think Waymo might get prices down to 65-95 cents per mile with fully matured tech that seems like good number.


Considering that's more than a cab costs in some European countries, driver included, I would say we aren't talking about commodity tech, but a highly profitable initial phase.


"A $30000 vehicle can drive 200K miles for the price of fuel and occasional cleaning."

Modern vehicles are incredibly more reliable than they used to be, but this seems to be overstating the case.


Self-driving people talk about this because, even if the tech worked, the costs of the hardware involved is currently so prohibitively high (~$100,000s per car) that a taxi model is the only one that makes sense.


In which case the capital costs of the vehicle will wipe out a good chunk of the cost savings from removing a human. Therefore, there will be no mass shift away from car ownership.


A $300k robotaxi could still undercut conventional taxi/rideshare, but the costs will have to come down considerably before they challenge the economics of personal vehicle ownership.


The comment beside you says that a car has a useful lifespan of 200,000 miles, or 50¢ per mile for the tech. The internet suggests the average highway speed in the US is 70mph. That suggests that it will cost $35/hr. for the autonomy and probably that much again for the car itself.

At $70/hr., I expect people will still opt to own their own vehicle.


When driving your own car at 70mph for an hour you are not getting that distant for free.


Certainly not, and in many cases it may even cost more than that to drive your own car. But the car comes with a huge advantage that taxis have fallen short on:

The cost is upfront. People sit down and budget $x for transportation and then they know that amount of money will get them anywhere they want to go. People hate having to decide in the moment whether they want to spend the money or not. I notice a similar phenomena when it comes to mobile phone service. People would rather pay extra for a plan that provides more than they could ever need than to have a lesser plan and pay overages when needed because the overages require thinking about it in the moment, rather than pre-planning how much they want to budget. $70/hr. isn't even going to have anyone thinking twice about changing their behaviour completely.

Maybe robs-taxi services will pioneer a pay ahead of time service that captures the necessary mindshare that will make ownership obsolete, but that won't have anything to do with the technology. There is nothing stopping a taxi service from doing that today with human drivers. It's just a tough business model to work with when providing services, so it is uncommon.


I wonder if self-driving over highways, coordinated with jitney-on-demand for the inner city route would be feasible ?


Not an expert but I believe controlling Lithium reserves is a great way of attracting companies that rely on Battery tech?

> I wouldn't be surprised if the plan is to move all WhatsApp users to Messenger. People use WhatsApp over messenger primarily because how "light" the app feels. It feels exactly like SMS for free, which was always the appeal of the app. Given the trend to make a Lite version of every Android app, Facebook should be prioritising WhatsApp, not planning to migrate it to Messenger.

PS - Has a mass migration of community from one product to the other ever been successfully pulled off?


The convergence of the Messenger and Whatsapp communities is all but imminent despite strong internal resistance from the Whatsapp team.

You don't need to migrate anything on the short run. The Whatsapp classic experience will probably remain the same for those who prefer the lite messenger, with the added feature of linking a Facebook account and talking to those people too. The heavy and encouraged experience will be Messenger, that already scours the phone book of those dumb enough to use it, and is perfectly positioned to talk to Whatsapp clients.

The massive network effect this move will unlock cannot be ignored by Facebook. I'm sure Whatsapp's privacy features will suffer, but users don't value them.


Digg to Reddit? Ha. Probably not what you were asking, I assume you actually mean within the same company?

Tencent did a reasonable job of migrating a lot of people to WeChat from QQ, but then again QQ is also still alive and used, so it wasn't a full/complete migration.


WA doesn’t require a Facebook account if FB does that they’ll end up losing quite a bit of users.


Nor does Messenger.


Adding some more relevant information:

India is having a digital revolution since the launch of Reliance Jio. They had launched a phone called as JioPhone [1]. This is powered by KaiOS, hence the market share of KaiOS in India has significantly increased. KaiOS is the second most popular mobile OS in India (ahead of iOS)[3].

JioPhone sold nearly 40 million units in the last quarter[2]! This is a huge market for Google to build apps for as well.
