Interesting; could this be because you've been using outdated C++ ? (legacy codebases started before C++98 tend to be particularly painful)

FWIW, I prefer the power of C++ over Rust's hand-holding; but can also see its appeal for someone that's not as confident over the minutia.

Not the person you asked, but for me (coming from C++20, with lambdas, async, etc), the big win is that the borrow checker automates away boring PR comments about "you used std::unique_ptr in a non-idiomatic way that is technically safe, and it bleeds memory unsafety into some random API, so write this level N+1 magic instead".

It also checks that all my threaded code is data race free.

On the downside, it's support for safe (in the sense that the compiler checks it) lock free programming is basically non-existent, which means that stuff that would be easy in C++ ends up being in Rust unsafe blocks that you need a PhD in type theory to reason about.

I'm not familiar with the C++ built-in facilities for lock-free stuff (but learning about them currently)

Could you expand on this if you're willing, maybe with some pseudocode?

I've also been curious about things like cache alignment, aligned memory, and false-sharing size detection in Rust -- all of which C++ has as std built-ins

Rust has atomic types that rely on interior mutability. No unsafe blocks are needed for those.

I think this is mischaracterization of why people choose Rust (and FWIW it comes across as condescending). People choose Rust over C++ partially for the same reason people write unit tests. We accept that no matter how good we are at writing software, we are still fallible, and so we introduce structures around our work to minimize the fallout from that fallibility.

No, it‘s exactly the opposite: I enjoyed C++ 11 but trying any feature tacked on beyond that just makes me want to smack my head onto my desk.

The standard isn‘t slowing down: for c++ 23 the committee has announced even more features when compilers haven‘t yet implemented every CPP 17 feature. What good is a standard if no one is following it?

It's not confidence, I just don't care. I don't want to learn the minutia of C++. Rust is the thing that has got me interested in lower level programming.
