> That's bullshit. If you develop on x86, then you're going to want to deploy on x86, because you'll be able to run what you test "at home" (and by "at home" I don't mean literally in your home, but in your work environment). I know lots of developers who work on macOS, and deploy to Linux. Back when Mac was PowerPC, I knew lots of developers who worked on PowerPC, and deployed to x86. Or worked on 32-bit, and deployed to 64-bit. Or worked on single-core, and deployed to multi-core. Or green threads to kernel threads. Or big RAM to small RAM. Or the opposite of all of these. This disaster he anticipates just doesn't seem to be a problem in practice. It's nice when your server is exactly the same as your workstation, but it's never been required. Even today, I have x86-64 on my desk and x86-64 on my server, but they're not the same CPUs, and they don't have the same features (or core count, or RAM, or OS, or ...). > Which in turn means that cloud providers will end up making more money from their x86 side, which means that they'll prioritize it, and any ARM offerings will be secondary and probably relegated to the mindless dregs (maybe front-end, maybe just static html, that kind of stuff). Are databases also "mindless dregs"? There's a lot of Postgres/MySQL/Mongo/... instances out there, and even if you're worried about the costs of porting, you only need to port those once (which AFAICT is already done for all of the major ones). If my database service told me they could cut my price by moving my Postgres instance to ARM, I'd click that button in a heartbeat. I have zero fear that anything would be fishy due to it being a different architecture than my workstation. > Do you really not understand? This isn't rocket science. This isn't some made up story. This is literally what happened, and what killed all the RISC vendors, and made x86 be the undisputed king of the hill of servers, to the point where everybody else is just a rounding error. I've worked with many companies, and in every case, going with x86 was 100% because of price. We didn't avoid SPARC or POWER or Itanium servers because of endianness or any other technical reason. It was just a lot more expensive. Likewise, we switched the servers to 64-bit when it was cost effective, not at the same time that our workstations switched.
