no, you can't build a big computer to model the financial markets

from forbes: I’m afraid this has to come under the title of one of the sillier ways of wasting the taxpayers’ money that has been recently advanced. The idea is to build a really big computer model of the financial markets and thus work out where and when they’re going to fail next. Sadly, the idea is going to fail itself, hopefully before anyone spends any money on it.
