GAs are not random. I do not get his manual block assembly part, though.

Size alone is a necessary but not sufficient condition.

On what evidence do you base this absurd optimism?

Once again, his neurons are highly simplified sketches. They are
Potyemkin's villages of neurons. The tasks of creating an AI and
neuronal emulation are only distantly related. Neuronal emulation is
distinctly harder.
