supercomputers

will they ever become perfect at chess... I guess there are a finite number of possible moves and therefore games (using 50-move-draw-ruling) so powerful enough computers will. How long until they can?

I think I read somewhere that there are "only" 10 with 126 zeros possible games in chess.

That's more than atoms in the known universe!

Can't you just time travel back to before you blundered? :p
