How would you know? Are you a programmer? It's not a bug but typical computer
behviour, we all know they can't think yet can toast you and grandmasters if
they are not on top of their game.

Can you calculate numbers faster than a dumb machine? No...does that mean they
are smart? No, computers have the advantage of speed and memory.
