Simulating a brain doesn't give you general purpose AI. Brains are useless. You can get one pretty easily, but what would you do with it? A brain without a body wouldn't be intelligent at all. So, ok, shift the goalposts to simulating a brain and a body. But that's not particularly intelligent either. If you dropped an adult human in the vacuum of space (with life support) nothing particularly intelligent would happen either. Ok, well shift the goalposts to simulating a brain and a body and an environment for it to live in. Still won't be intelligent. Humans raised without any socialization have serious cognitive defects. Not really "intelligent" for our purposes. Well, so simulate a brain in a body and a social environment. No we've introduced a chicken and egg problem. Maybe you give the AI a robot body and allow it to live amongst humans. That would work, and also removes the need to simulate the environment. A huge win. But is that any different than a human human? Ok, you want this virtual brain to be way bigger... 100x the neurons of a human. But still with the human body and socialization. How is that different than a human with a cloud-connected smartphone? Right, bandwidth. Elon musk says a smartphone doesn't have enough bandwidth and we need a BCI. But raw UI bandwidth doesn't seem tk have increased for a couple decades now. Smartphones actually have less bandwidth than laptops. But we keep being able to do more and more with better software. Is bandwidth really the limitation? And if bandwidth isn't the limitation, does an AI really have an advantage over a cloud-augmented human brain?
