Could Google hit $2,000 a share? Henry Blodget thinks so, but I'm not so sure. That would value GOOG at $750 billion — roughly the same as Microsoft ($279 billion), General Electric ($431 billion), and News Corp. ($70 billion) added together. And that's assuming that none of those companies grow at all — a highly unlikely proposition. Could Google be the first company worth a trillion dollars? Maybe, but I'm not placing any bets in the "first-to-a-trillion" Valleywag office pool. Remember how well predictions of a trillion-dollar market cap worked out for AOL Time Warner?
