1. Requires data connection, either WiFi or mobile data. SMS does not.
2. On Android, it goes through Google Messages. I don't trust Google.
So, I replaced Messages with another SMS app that doesn't spy on me and disabled RCS. If I wanted to do rich messaging through data connection, I would use Signal or similar.
So, RCS is not a replacement for SMS. It's just another IM protocol. And we have enough of those.
As for others replying through RCS, that's a failure of the messaging app, should recognize that the counterpart is SMS and reply in SMS. It's an attempt to force RCS...
SMS is for fast short messaging between mobile users, and that is its killer feature, it's universal. Every mobile phone supports it.
Signal dropping SMS support makes no difference for me, never used it for SMS, I used Signal for the secure conversations. Two different methods of contact.

3rd party SMS apps use a Google provided API to send and receive SMS messages on an operating system provided by Google. I'm not sure how you think using a 3rd party SMS app would be protecting you if Google cared about spying on your messages.
RCS through Google Messages is end to end encrypted while SMS is not, so you haven't eliminated Google in theory spying on your messages but you have assured that your carrier, the recipients carrier and whomever controls the OS and app on the destination device can potentially spy on your messages.
1. True RCS isn't supposed to go through internet, it's supposed to go through same way as SMS and voice calls (which is also a data connection, but specific to sms/rcs/voice)
2. That's not a requirement even though Google does their best to kill all alternative implementations. (Samsung had one, but Google paid them a lot of money to get rid of it. I have to admit I don't know who is left with their own RCS client)
> So, RCS is not a replacement for SMS.
It's 100% a replacement to SMS, it's literally defined in the same spec as SMS over LTE, as an upgrade to SMS. Though yeah Google made it, this... uh... thing. RCS is technically a federated standard, but Google killed every part of the federation and some parts of the standard.
This is interesting, but no mention of how the hosts process these molecules. We all know that our body has problems processing artificial molecules (artificial sweeteners, etc).
In 1996 or 97, a friend brought me his Compaq Deskpro, the SCSI HDD had stopped working. No sound at all, dead. Tried everything, checked voltages, reconnected cables trying to clear any oxidation. Wouldn't spin at all. Well, called it a night.
Next day, decided to take it out of the chassis for a last test, connected outside. Not only it spun, it worked fine!!! WTH????
Well, into the chassis it went. Nothing. Dead. Whaa..??? Outside again, it worked. In the chassis, dead. Outside, worked. Scratched my head... With it working outside, just tried to place it on top of the chassis. It spun down and stopped. Took it away, it spun up. Got it close again to the chassis, it spun down again... Scratched my head again... Gave up, left it disconnected outside for the day.
Next day tried it again and this time it worked outside of and in the chassis... My thoughts? The chassis was magnetized or something...
Perhaps a defect in a cable or connector such as a broken wire or a dry solder joint? These often cause problems that mysteriously appear or disappear as the cable is moved and the changing forces on the defect make and break the connection.
Nope, I tried everything, twisted the cables, etc. I even changed from power connector to another and changed SCSI cable. Outside it worked, inside didn't. Working perfectly outside, as soon it got close to the metal of the chassis it spun down, and as it got away from the metal it spun up.
Do you know about dosdude's Catalina patcher? And for previous versions? It's unofficial, so it might not suit you at all. It allows older hardware to run (with some caveats) newer macOS versions.
Just an FYI, at least on previous patchers it turns off SIP. I’ve turned it back on and haven’t had an issue, but it does display a warning on boot that things may not work.
The Atari ST line of computers also use DB-19 connectors for their external ACSI interface, usually used for connecting hard disk drives. ACSI is Atari Computer Systems Interface, similar to SCSI.
It was possible to hand-make a replacement for Atari's external floppy drive (round DIN connector on the right) because Atari wanted too much money for theirs. Having two floppies meant that compiling went from several disk-swaps to no-swap happiness.
