If anything, better hardware is just an enabling technology for programming languages that run their static analysis at compile time. Rustc is written in Rust - it's not like it's going to get 10x faster any time soon.
More hardware means you can do more things. Yes, lots of software is slow and bloated for no reason. But sometimes you want to be able to do more than the current hardware allows.
And it's not like the rustc devs haven't been working on performance improvements.
it is scary how delusional and inefficient "modern" developers are
