there's a sweet spot, obviously if you go too low you're talking about barely autonomous people


sigh singularity hypothesis requires no "accelerating change" any eventually upward slope will do.


Max Weber's theories on Protestantism being the cause of success in America have been pretty much thoroughly debunked when you control for differences in aptitude amongst the religious sects that arrived to America in it's early history. Not to mention his work led to the founding ideas of the Frankfurt School lol.


This post is just a bunch of nonsense.

His theories on the Protestant ethic are controversial[1], but hardly "thoroughly debunked." As far as the Frankfurt School, uh, who cares? They drew from many political and social philosophies (including Marx who we often find at odds with Weber). It just seems completely uncharitable and tangential to bring it up.

Bringing them up in a negative way is usually used as a dogwhistle for people that believe in the "cultural Marxism" conspiracy.


While Weber over-stated his case, he has definitely not been "debunked". Check out _Causes and Consequences of the Protestant Reformation_ by Becker et al[0], it's a survey of the literature and contains a lot of empirical evidence in support of the Weberian view of the Reformation.

One thing I found out from interviewing a lot (for junior-ish positions) was that dynamic programming questions are actually your friend. Since it's a "hard topic" they give you a relatively easy one that can be solved using brute force recursion with memoization slapped on top so it takes like 5-10 mins and looks super impressive.


But for which companies?

For some reason I doubt that would work for the Big4+Unicorn interviews - then again, I've never gotten a DP problem from those companies.


He has Ezra Klein voice. Or maybe it's called NPR voice.


Would Sam talk to someone higher status with a fry voice, like he couldn't be bothered to muster the energy to speak normally? No. Vocal fry is used to show that the speaker is higher status. Genuinely high status people don't use it because it's a passive-aggressive way to show higher status.


I believe the author himself said that computation improvements does make it easier to solve general AI. I think in value alignment theory there are still problems that they don't know how to do properly even with infinite computation though.


Stopped reading this comment after "Gladwell".


Contentiousness is a ~50% heritable personality trait, only slightly less than IQ.


If you repeat the word "collapse" enough you can trick your brain into thinking you've actually explained something :P


How convenient that this supposed "spooky action at a distance" can't actually send information ftl. Locality is very important for coherent laws of physics. Many worlds is still the most parsimonious explanation which is why it enjoys the most support from theoretical physicists. It's literally just extrapolating what we already see in small scale experiments to the macro scale, it's staring you in the face!


Could you touch on why many worlds is more parsimonious than pilot wave? I'm not sure that I understand that reasoning. Is it because a given "universe" is locally simpler? Would it be accurate to describe the comparison as an infinite number of universes (separated via some higher dimension) vs. a single universe that is holistically connected throughout spacetime?


The theory is more parsimonious. Whether it generates untold amounts of parallel universes is immaterial to its own Kolmogorov complexity.

Many worlds basically says "the wave function is real". You just take what the math says at face value, and the math says there's a blob of amplitude where the cat is alive, and another blob of amplitude where the cat is dead, and those blobs do not interact.

Copenhagen adds something on top of the math: a kind of "collapse" where the blob you did not observe gets mysteriously zeroed out. There's only one universe, which looks simpler, but the theory itself is more complex, because you just added that collapse.

Pilot Wave (of which I know nothing) seems to add a similar complexity. There's no collapse, but there's this additional non-local "wave" that's laid out on top of everything, and determines which of the blobs is real (the dead cat blob or the live cat blob).

Think Chess vs Go. Chess has rather complex rules, with an initial position, moves for 6 different pieces, and a couple special cases. Go's rules on the other hand can fit on one page. So, Go is simpler. However, in terms of possibilities, the universe generated by the Go rules is orders of magnitudes bigger than Chess'. Simpler rules can lead to more diverse possibilities. Quantum physics interpretations are similar: Many Worlds have the simplest rules, but it also describes the biggest universe.


Can I just say this was very beautifully laid out. Much simpler and more convincing than what I could have done. Thank you.


However, doesn't many worlds also necessarily require one or more dimensions for separating the universes from each other?


Actually, configuration space have an infinite number of dimensions. Current physics, (or at least QM) doesn't describe our universe as having 3 spatial dimensions. That's a projection, the classical illusion —which is a logical consequences of the underlying physics of course.

Imagine 2 pearls on a thread. You have 2 ways to represent them: the obvious one is 2 points on a line. A less obvious (but just as valid) is a single point on a plane: the X axis would represent the first pearl, and the Y axis would represent the second pearl. Similarly, 2 billiard balls on a billiard can be represented by a single point in a 4 dimension configuration space. And the entire universe require many many more dimensions than that.

There are many more subtleties. I suggest you read the Quantum Physics Sequence for a comprehensible explanation of all this mess. http://lesswrong.com/lw/r5/the_quantum_physics_sequence/


Many worlds is parsimonious in some ways in that all the stuff allowed by the equations happens and that's it (sort of in theory at any rate - not sure it really gives the Born rule). With pilot wave or Copenhagen you have to tack on a wave or observer respectively. On the other hand all the stuff is a lot of stuff.


The complexity of a theory is in how long the theory itself is, not how big the objects it generates are. The peano axioms are extremely simple, despite generating an Infinity of numbers.
