IMHO - one of the skills we still need to cultivate is "How do I know the information this machine is giving me is accurate?". During my time in school (an engineering-oriented college even though I am not an engineer) they consistently reminded us that even though we have calculators, we still need to have an idea if the result "looks right". One can generalize this to results from a search engine.

Of course - then we program this heuristic into the search engine and then what? :-) [edit] I feel this is one of the things about IBM's "Watson" which was truly revolutionary.
