Higher reasoning evolved in humans over a short period of time. … The human brain should be seen as evidence that a certain scale is ~sufficient, but not that it is necessary.
We can still see that a chimp scale brain with this architecture isn’t sufficient, and human-built AI architectures were also only developed over a short period of time. Backprop and large scale training in parallel for one individual might give AIs an advantage that chimp/human brains don’t have, but unclear if this overcomes the widely applicable unhobbling from the much longer efforts by evolution to build minds for efficient online learning robots.
