Progress measured in what?
Total thinking power measured in what?
Can you cite any data backing up this idea of yours?

That's an ad hoc number. No one really knows.

Naked CPUs don't compute, computers compute. Computers are not all-purpose
machines as far as neuronal processing is concerned, so you would to have
to run a benchmark. Notice that you're assuming embarassingly parallel
code here.

There's no abstract computer "power". You have to have to run your
specific benchmark. It's not obvious that we'll have all-purpose molecular
circuitry in ~two decades, allowing a smooth transition from semiconductor
photolitho to self-assembled molecular circuitry.

Measured in what?
AI is the archetypal thresholded development. All the hardware in the
world under your fingertips is worth jack as long as you don't know how to
use it.
