I think it’s a combo of this and the fact that “intelligence” continues to not scale with the inputs as they’d hoped. I haven’t been keeping up with developments, but it feels like they’re finding new ways to discover that the brain is in fact an miraculously efficient and effective mechanism. Most their party tricks seem to be reproducing brains more minor processing feats in interesting ways. All the promised advancements have stagnated and what remains is just exploitation of economies of scale and its consequences, which is far from the revolution investors were promised.
