Research Program
Has anyone heard of the Mathematica programs? If so, have you heard if it is good or not? Seems like an ultra-sophisticated version of Wikipedia that can also do some thinking for you to boot. We may buy it for research (computed visual), but it' always prudent to ask for some testimonials...
(I happen to think that, if at some point we create artificial intelligence, programs like this, if they live up to their hype, will be the major stepping stones.Geographical Information Systems is another contender.)
