People want to replace C, which runs anywhere. Rust must also be able to.

Rust is a replacement for C++; if you look for a C replacement you should look on Zig

Pity that it is as good as C in producing UAF exploits, and doesn't have any story for binary libraries.

C doesn't run in 8 bit and DSP computers that well, dialects of it do though.

And Rust does better??

The point being that C doesn't really run anywhere.

Yeah but does Doom run on rust-analyzer?

Rust analzyer type checks rust and type checking is turing complete... it's only a matter of time.
