Evolution has taken us through an uncountable number of neurons and lifespans. In my opinion, even if we had an AI that matched performance of the human brain, it'd still be missing the historical data on earth (and the universe) we used to arrive at this point, the level of parallelization that exists across the earth across all life forms, and the capacity to input as much data as all life on earth can. Data and input capacity are as important as the model in machine learning. I think we sometimes forget how interdependent we are. We learn a lot through sharing our experiences, and when there are more of us, we make more breakthroughs as a species. And, maybe the answer is 42.
