I agree with regards to lock-free not being faster than lock-based, but that: > replace threads with separate processes that communicate via ring buffers does not follow at all. Interprocess communication is always more work to set up

For what it's worth, I think it's great that you are willing to at least reconsider the pros/cons of Rust when presented to you, even if it's not enough to change your mind. I believe your issue with the "Rust hype&

Not that much, but I imagine a lot of bars would spring up in the vicinity of iron electrolysis plants, on account of the steady supply of cheaply transported beer.

Ray-tracing is absolutely trivial to parallelize, because every pixel is computed independently of all others. That would even be trivial to parallelize in C, and that's saying a lot!

That is misleading. Although you're technically correct [1], the computational models on which computational complexity classes are based are so abstract and idealized, that they offer almost no information whether your program could m

Yes, you're probably right. Frankly, I'd rather not have this kind or error-prone behavior in my programming languages, not even when scripting. It makes proper handling of strings hard and cumbersome (as evidenced by a lot of sof
