If we all stopped complaining about memory safety in C and C++, we would never have gotten rust in the first place. Rob pike would never have let generics make it into Go if people didn’t spend years pestering him about it.

I think I fail by taking for granted all the work that’s gone into languages like rust. Lots of smart people have poured themselves into these discussions and designs. Thankyou. I don’t say that enough.

But yeah, async rust seems like one of those places where people arguing it out on github didn’t converge at a great design. It’s a really hard problem - really, combining a borrow checker with stack suspension is a CS research problem. I think it’s interesting and important to acknowledge that committees don’t always do great research. Sometimes you need a bunch of iterations of an idea. And a bright cookie or two who can work without justifying their designs.

So no, I don’t think I’ll stop talking about it. Making async rust v1 was an incredible amount of work and I’m very grateful. But I also really want to seed the idea space so some bright sparks can think about what async rust v2 might look like.
