I have doubts about your statement.

The particular problem here is it's not addressing the intelligence spikiness between individual humans. Most humans aren't going to play a competitive game of MTG, a small percentage will rise above the rest and dominate.

Also this is being intelligence blind. Most humans could never write a good python script to play a competitive game of MTG, almost any SOTA model can.

This would be like a bee saying humans aren't intelligent because we can't see in ultra violet, where as we're damn good at making tools that can.
