The brain definitely has an edge on compute power. The computer has an edge on storage power. I would bet the brain doesn’t store more than a Terabyte of information.

We just need more cores without spiking energy usage.

The human brain has over 100 trillion synapses, which is somewhat analogous to storage or memory (in both senses). Some estimates for the storage capacity of the brain are as low as a terabyte. Others are an order of magnitude or two higher.

Being electrochemical, the brain is “slow” compared to a computer (around 10hz). But it’s massively parallel and an interesting combination of digital and analogue.

Considering the kinds of experiments that have occurred in the past on electrical stimulation of the brain and memory recall, I would say that the amount of memory being used in the brain exceeds any limit we may well put on it by many, many orders of magnitude.

The major problem is that we are not trained today to recall most of what gets laid down. We are far to dependent of external storage mechanisms, books, videos, etc, that we no longer train ourselves to actually recall and pass on our knowledge.

I am not saying that external memory is bad, just that we should be using all options available to us.

Our understanding of the brain and its mechanisms is very much in the very early stages - we have just scratched the surface.

Interesting observation. I think most of us rely on some sort of world view or paradigm to operate. Probably as a result, the actual info stored is even less than a TB.
The computer also has an edge on precision and determinism.
Erm, and we just need the software to run it all :)
