Very interesting read. It raised a few questions/comments in my mind.

Is it even possible to fully understand how the brain works? ie can the brain comprehend itself. Computers on the other hand are 100% understood since they are a product of our minds.

The human brain is several billion years in the making starting with the most simple organisms. Although they have come far, computers are still very new technology even in human terms. Even the latest and greatest new processors are just faster versions of 30 years old ones. Who knows what path will be taken in the next 100 years, let alone 1000 or more. Perhaps the computers of the future (All this talk of transistors and binary logic and such will be nonsense) will operate more like the human brain. This could be unintentional however, because the ideas which lead to new developments don't necessarily reflect the brain processes which lead to them, and it could be only coincidence that the end result operates like the brain. Or perhaps computers will become very different from our brains to the point where analogies like the ones in the lecture are hard to make. After all, the whole point of computers is to do things that our brains cannot - would purposefully copying the brain be a wise choice given such a goal?
