>following along the last few years the promise was for “exponential progress”

I've been following for many years and the main exponential thing has been the Moore's law like growth in compute. Compute per dollar is probably the best tracking one and has done a steady doubling every couple of years or so for decades. It's exponential but quite a leisurely exponential.

The recent hype of the last couple of years is more dot com bubble like and going ahead of trend but will quite likely drop back.
