Artificial intelligence is like a brain without a body. Instead of billions of neurons, computers contain bits and bytes of varying voltage levels so it can do stuff like provide directions or beat humans at chess.
Deep Blue beat Kasparov not by matching his insight and intuition but by overwhelming him with blind calculation. Thanks to years of exponential gains in processing speed, combined with steady improvements in the efficiency of search algorithms, the computer was able to comb through enough possible moves in a short enough time to outduel the champion.
Machines have faster processors. Even the most effective Ritalin in the world would leave a person at a loss. Yet, AI is a factory of nothingness without human programming. It is ‘competent without comprehension,’ although the human mind often falls guilty to automatic pilot.
