Ok, but it's a bit odd that you kept reacting with incredulity at people not knowing that fib was THE parallel example to know, and then it turns out it's a poor example because synchronous fib with memoization (which is the way many people learn it in any early CS class, and which wouldn't be possible async) is so much faster.

I think maybe if there hadn't been such a vibe of "what, you don't know X?!?" then it would have just been an interesting fact to mention that parallelization demos often use fib, because it's an easy example to grok (though a confusing one if you already understand the faster method).
