> with very strict guidelines.

Low level languages always came with a set of usage guidelines. Either you make the language safe for anyone that they can't shoot themselves in the foot and end up sacrificing performance, or provide guidelines on how to use it while retaining the ability to extract maximum performance from the hardware.

C/C++ shouldn't be approached like programming in Javascript/Python/Perl.

And yet, Rust doesn't sacrifice performance and it has all kinds of those guardrails.

I think it is a bit myth that Rust does not sacrifice performance. If you stick to the safe part Rust usually does not seem to achieve the performance of C/C++ according to what I have seen and read. I agree that the cleaner separation of unsafe and safe parts is an advantage of Rust.

The clean separation between Unsafe and Safe rust is precisely, IMO, one of its biggest advantages (and the reason why it'll be superior to almost anything C++ comes up with).
