Yeah, I agree. But the ideas of mechanical sympathy carry over into more than one kind of design. You can still be thinking about caches and branch prediction while writing things in async. It's just the awareness of it that allows you to make the tradeoffs you care about.

Eh... not really. The main problem is that it becomes incredibly hard to reason about the exact sequencing of things (which matters a lot for mechanical sympathy) in async world.
