I'm not sure how you got the perception that we're going "all in" on green threads, given that the article in OP explicitly mentions that we're hoping to have an implementation based on stackless coroutines, based on this Zig language proposal: https://github.com/ziglang/zig/issues/23446

Performance matters; we're not planning to forget that. If fibers turn out to have unacceptable performance characteristics, then they won't become a widely used implementation. Nothing discussed in this article precludes stackless coroutines from backing the "general purpose" `Io` implementation if that turns out to be the best approach.

That is lovely to hear. I think the general conscious is that not a single programming language has done Async right. So people are a little sceptical. But Andrew and the team so far seems to have the do it right mentality. So I guess people should be a little more optimistic.

Cant wait for 0.15 coming out soon.

I would argue that Java's async is pretty nifty, especially now that some of the rough edges have been sanded off.

What is wrong with async in JS?

Does the BDFL want this though, or is it just one person's opinion that it might be nice? Given how he has been aggressively pruning proposals, I don't put any hope in them anymore unless I see some kind of positive signal from him directly.

e.g. I'd feel a lot more confident if he had made the coroutine language feature a hard dependency of the writergate refactor.
