Computers will dominate our world!!
We just need to make certain WE stay in control, and so far we are. Computer chess playing programs already play much better than the best humans, and are faster. To give some perspective, even a low level chess player as myself can beat 98% of the population. Grand master chess players are the very best human players and would beat me every time. But put them against the best chess playing engines and they will feel as they have won when they simply draw a game! Too, humans just don't have the stamina to keep up with machines that can focus all their energy on one task. Machines never get tired - humans get exhausted!
