Isn't that the point of the end of that comment?
This acknowledges that the "optimizing a hand of cards" analogy leaves out factors -- which is true.
My point is, even if there were no emotions or institutional knowledge, even if I had a "staff" of AI agents or robots whose "knowledge" could be fluidly copy-pasted, the "optimizing a hand of cards" analogy is poor, because a robot that makes money is worth keeping even if there are better robots out there. An army of low-but-positive ROI robots can help me buy a high ROI robot.
