Fuzzy Pattern Spotting
"Computers just crunch numbers, and find patterns" - but the pattern recognition abilities of the human brain far exceed any computer program we've yet developed. A human forecaster can look at a weather map and instantly see the patterns where a computer would have to do an enormous amount of number crunching to find them. The human has no problem relating these patterns to similar patterns seen before (though they're never identical), while this is a very complex problem for a computer.
The ability to identify patterns hidden in a complex of irrelevant data was a vital survival skill to our ancestors - spotting the lion that's hidden in the bushes could save your life. Millions of years of natural selection have refined this skill in us, little wonder it's taking some time to develop computers that can rival us.
