As a programmer, I hope that your answer continues to abstract away the problems of concurrency from me, the way that CPU designers have managed, so that I can still think sequentially except when I need to. (And as a senior engineer, you need to — developing reliable concurrent systems is like pilots landing planes in bad weather, part of the job.)

I was doing some Java code recently after spending a decade in async code and boy that first few minutes was like jumping into a cold pool. Took me a moment to switch gears back to everything is blocking and that function just takes 500ms sometimes, waiting for IO.
