There's a duality of thought going on here (with apologies to the false dichotomy). One says that all intelligence is ultimately materialistic/mechanical and that all we must do is retrace these steps with electronics and we can achieve whatever we want including high-value traders. The other seems to leave room for... let's call it the "irrational" side of things.

My only point here is that just about all values themselves are irrational. The same problem in trying to get a computer to recognize that the Mona Lisa (or poched eggs or Mozart or whatever) have value, is the same one that makes it hard to teach them to figure out if Tesla is still a good long-term investment etc.
