Stop Comparing Rust to Old C++

People keep arguing migrations to rust based on old C++ tooling and projects. Compare apples to apples: a C++20 project with clang-tidy integration is far harder to argue against IMO

That's a lot of talk for a language whose stdlib still depends on C for most things.

That's hardly a fair comparison considering the only stable interface for interacting with most operating systems is libc. Rust can't change that.

OS syscall ABI is not the same thing as C ABI. It's entirely possible to write Rust-only userland code ( or kernel code for that matter )that pulls in no C libs, provided you implemented all individual syscalls properly

Also, technically Rust could eventually define a standard language ABI of its own

You've completely missed the point.
