Regarding your edit, I'd wager that it won't stay true for long. Eventually the single-function problem of orchestrating and directing a bunch of sub-solvers in a similar manner to the human brain will become feasible. At that point true general purpose AI will exist, for all intents and purposes.
And when that happens I guarantee someone will be on HN saying it is "trivial" and "not a real advancement" and "we already basically knew how to do this". Because that's what people say every time something interesting happens in AI, without fail.
