The adult brain is different from a newborn's because
​ ​
it has learned from
​ ​
events in the environment, but so would a
AI. The question is how complicated does a machine have to be to
​be ​
able to learn and become intelligent at a human level? Well, the entire
human genome is 750 meg with about half of that used for the brain, so at
most the instructions for building a seed AI would have to be about 375
meg,  and almost certainly less than that and probably a lot less.

​True, but once the seed AI is built humans no longer have to understand
how it's mind works, we just introduce it to the world and let it learn
stuff just as we do with a human child. ​

​I think so too but like you it's only a hunch and I could be wrong.​

​But I think once machine intelligence has been achieved, either by AI or
reverse engineering the human brain and uploading, nothing will take very
long anymore; things will start to change at a breakneck pace. And I mean
that literally, human biological necks could very well end up getting
broken.   ​
