There are a lot of AI problems that can be solved with less than human intelligence but some human numbers for reference: By the time you're 30 you have been exposed to: ~1.4 petabytes of visual information ~1.8 terabytes of auditory information Touch and proprioceptive bandwidth is harder to calculate but the ascending pathway through the spinal cord is about 10 million fibers, which is 10x the optic nerve (Or 5x the number of fibers from both eyes). So: Between 1.4 and 14 petabytes of touch and proprioceptive information. So we're a fairly large data problem on top of millions of years of evolution that have baked in some knowledge and abilities.

Not really. Our knowledge takes shape way, way before we hit 30 in every area you can think of. Some modular brain systems actually come to full form in the few first years, some in the few months (vision). I would argue that the data we exposed to is not only small, but actually sparse.

  If you consider brain development to be iterative over many generations of brains through human and pre-human history, the training datasets are a lot larger.

    Except that doesn't make sense. The complexity of changes that can be carried over is very, very small compared to the changes which go on in a single lifetime. And the mechanism is totally different.

How did you get those numbers?

Do these numbers take into account that most of the information reaching the eye never reaches the brain? It is amazing how little information is transmitted from the eye to the brain - the vivid images that we "see" is to a large extent product of the brain's own imagination, with impulses from the eye to a large extent only provides limited, 'corrective' information to ensure acceptable coherence with reality...

  Yes these are all based on the bandwidth of major nerves. As well as time awake.
