I was thinking more of my workstation. If I lose access to free software, I might as well just leave the whole industry and stop using technology.

It is kind of important for me I do not have to use closed source blobs or operating systems. And I think I'm not the only one.

Btw, I've yet to see a Graviton instance that compiles our Rust project faster than my 3090x workstation. Maybe there is, but it costs a fortune. And what Amazon does here is it just kicks out all competition who cannot build their own CPUs. Then they can ramp up the prices.

¯\_(ツ)_/¯ I'm with you on not enjoying loss of access to my hardware and getting further and further away from the metal. But also, we gotta make a living and pay the bills... it's a competitive disadvantage with online services to be using more expensive to run instances.

In my experience and testing Rust lang is lagging a bit with ARM support. It's not that the language doesn't have good support (it does, it's great and very easy to cross compile), it's that the ecosystem around rust is _very_ x86 focused. Like I saw a simple JSON parsing library decided it would be cool to add SSE and SIMD support and now it doesn't work well on ARM (which has a totally different set of SIMD extensions). I have a strong suspicion your rust projects depend on libs with similar issues--but be ready because once those libs support similar optimizations for ARM, it's going to be super fast.
