Rcently, the world was told that a computer program named Alpha Zero had learned how to beat Stockfish in chess. Stockfish is generally accepted to be one of the world’s best chess computer programs (if not the best), and since I am a fan of the game, and of artificial intelligence (AI), this caught my attention.

The fact that Alpha Zero won by learning about chess in a completely different way than any other popular chess program made people sit up. But I must confess that not everybody around me shared my enthusiasm.
