Furthermore, the brain is massively parallel, and has a specialized architecture. For what it does, it's well optimized, at least compared to how optimized our software and hardware are for similar tasks at this point. For instance, laptop processors are general purpose processors, being able to do many different tasks they aren't really fast or good at any.

Intuitively this doesn't seem right at all: I can think of plenty of things that a human plus an external memory aid (like a pencil + paper) can do that a laptop can't, but (aside from dumb hardware stuff like "connect to the internet" and so on) I can't think of anything for which the reverse is true; while I can think of plenty of things that they both can do, but a laptop can do much faster. Or am I misinterpreting you?
