What makes it "much more obvious that it is possible" to simulate the human brain? If you're thinking of artificial neural nets, those clearly have nothing to do with human intelligence, which was very obviously not learned by training on millions of examples of human intelligence; that would have been a complete non-starter. But that's all that artificial neural nets can do, learn from examples of the outputs of human intelligence.

It is just as clear that there is one more ability that human brains have, than the ability to learn from observations, and that's the ability to reason from what is already known, without training on any more observations. That is how we can deal with novel situations that we have never experienced before. Without this ability, a system is forever doomed to be trapped in the proximal consequences of what it has observed.

And it is just as clear that neural nets are completely incapable of doing anything remotely like reasoning, much as the people in the neural nets community keep trying, and trying. The branch of AI that Lighthill almost dealt a lethal blow to (his idiotic report brought about the first AI winter), the branch of AI inaugurated and championed by McCarthy, Michie, Simon and Newell, Shannon, and others, is thankfully still going and still studying the subject of reasoning- and making plenty of progress, while flying under the hype.
