Meh, Y combinator has already helped to solve that.
The problem is Google is wasting investor money trying to be a big company, recruiting thousands of employees and trying to expand rapidly. Why not just stay small and efficient with respect to their core search and advertising services, and just buy startups if they want to expand in other areas?
Edit: Seriously. It’s a classic and universal problem. It’s hard to solve, and interesting. Most organizations attack it using an ad hoc grouping of traditional measures and panic.
