What's the difference between a human's brain and AI?

When I was very young, a magazine gave instructions on how to make an “AI” (not called AI at that time) which could play a mini-checkers game. You could make it with a bunch of penny match boxes (showing my age) and sets of different colored marbles. Each board position was cut from the magazine and pasted to a match box which had different marbles in it which indicated the next move. When it was the AI’s turn to play, you would select a marble from the box. If its move lost, the marble played was removed from the box, leaving only a winning move. In other words. Eventually, only winning moves were left and the AI (made of match boxes and marbles) could not lose. This example refutes the claims people frequently made by people comparing the brain and AI, such as… “An AI can’t learn by experience.” The point of this example was that it DOES learn by experience. “An AI can only do what it’s programmed to do.” — No programming, no algorithms, not even a computer was involved.
