I think you're badly mistaking what I'm talking about with "looking up answers" - what I'm talking about is considerably more than that.
How efficient will planar electroluminescent backlights be in 10 years? That's a good question - and one we can make an educated stab at given the right historical data, the right experience in forecasting, and a little bit of plain luck. Heck, you're now talking about an entire field of mathematics and engineering in and of itself!
Compare this to the Google interview though - where they expect you to pull a number out of your ass, with no opportunity to consult historical data, no field experts to interview... no due diligence done at all. It is either an extremely poor approximation of real-life problem solving skills, or everyone at Google is recklessly cowboy and trying to deduce every decision ever by sheer will of logic alone.
