Cutting edge supercomputer programs get judged by different standards from basic forms.

And when slow is the only option, people will wait.

Ding ding, you nailed my point.

Weird, because I completely agree with FridgeSeal.

Decent performance is table stakes outside of very special contexts, and software that can't manage it is bad.

Finding an exception doesn't make that stop being true in general.

Speed is always relative, otherwise it's a subjective, and thus less interesting metric (it's slow for you, not for me).

Stable diffusion is not relatively slow, because it has no alternative that is noticeably faster.

It’s fine to take time to crunch output. What needs to be fast is interaction. If it tells you “Hang on I’m working on it” I don’t think anyone minds that as long as you can leave it to cook while doing something else.
