The whole point is that intelligence is a concept that points at a bundle of related characteristics.
There is one indication that Deep blue is more intelligent than a toddler - it can beat the toddler at a game of chess.
There are other indications that a toddler is more intelligent than deep blue - they could write better poetry, play tic-tac-toe better, play checkers better, play, well, literally _any_ other game better, do arithmetic better, etc.
So on one metric DB is more intelligent. On every other metric the toddler is more intelligent.
Is it actually an indication that Deep Blue is more intelligent, or does it turn out that Deep Blue is succeeding at chess by means other than intelligence?
So on one metric DB is more intelligent. On every other metric the toddler is more intelligent.
