Truth detection software?

The founder of Google thinks that "truth detection" software will exist in five years.

He's wrong, it already exists in the form of Google and other search engines. It's the Age of Google, and people who peddle phony stories, like fake memos purporting to show someone was AWOL, won't be able to do so. You also can't hide stories, either, like the discovery of weapons of mass destruction in Iraq (500 shells with sarin and mustard gas). You can also find out the background of a person who makes a scene with a politician.

The truth can be found - and revealed - setting everyone free.
