Paul Graham says Google doesn't want to follow anybody down that road (human intervention in search). But ISTM the problem is that even though they don't, they can just throw a giant pile of money at it if they needed to crush a competitor. Also, VC will refuse to invest in anybody doing it because Google.

PaulG doesn’t know what he’s talking about.

I disagree, he's a pretty good guide to how VCs think, though not always in the ways he wants.
