With semiconductors, Moore could see that we were nowhere near fundamental limits of our ability to scale processes. With AI... are we? I certainly don't know; I'm not sure that anyone else does, either.
Scaling down to smaller features was just dealing with assembling atoms. You could see that, while there was a lot of work to do, we had room to keep going. But AI is dealing with algorithms, and how do you know whether there's still exponential room to improve?
