I believe that AGI cannot be exponential for long because any intelligent agent can only approach nature's limits asymptotically. The first company with AGI will be about as much ahead as, say, the first company with electrical generators [1]. A lot of science fiction about a technological singularity assumes that AGI will discover and apply new physics to develop currently-believed-impossible inventions, but I don't…
I don't recall editing my message, but HN can be wonky sometimes. :) Nothing is truly exponential for long, but the logistic curve could be big enough to do almost anything if you get imaginative. Without new physics, there are still some places where we can do some amazing things with the equivalent of several trillion dollars of applied R&D, which AGI gets you.
It astounds me that people dont realize how much of this cutting edge science stuff literally does NOT happen overnight, and not even close to that; typically it takes on the order of decades!
