Thinking that external developers can't work on those layers if publicized is a bit juvenile, IMO. :)

We have open source projects with layers upon layers of abstraction tackling problems equally if not more sophisticated than Google search.

Developers involved in those problems are not juvenile, IMO :), and I bet some of them would like to work on Google's "sophisticated" layers.

Next time you disagree with some idea, present your arguments in a mature way. Casting demeaning personal judgements like "juvenile" is not mature, IMO. :)
