What do you mean by "comprehend"? What do you say to the idea that we might -- rather than build an AI piece by piece and thought by thought, a project I agree is several orders of magnitude beyond our ability to comprehend -- instead "grow" an AI by putting together evolutionary computation and enough processing power to eventually converge on something we would understand as "intelligence"? The extent of such an intelligence wouldn't be fully understood by us, or itself for that matter, but what of it? Our intelligence evolved without anyone understanding it.
