Yeah, I was slightly sloppy about that, but also the distinction doesn't entirely help at this level because people get into vicious fights about whether a particular bit of complexity is really "necessary". E.g., lots of people argue that async Rust is unnecessary complication, either because you can just write all the state machines by hand (which is terrible for expressiveness, but do you really need expressiveness?), or because you can just spawn an OS thread for every task (which is terrible for performance, but do you really need performance?). Whereas the pro-async perspective is, yes, it's very complex, but nothing simpler would have done everything that it needs to do.
Oh, I hear ya. That makes perfect sense, and you're so right: my idea of a complex solution might be someone else's complication, and vice versa. I didn't mean to disagree with you, and surely not to correct you, because not everyone agrees on the distinction I make between the ideas.
I meant that more in the spirit of "oh, while we're talking about this, here are my thoughts on a tangentially related idea".
