Here is why the statement is way too optimistic:
- Resources always move to places where they can be used most effectively (econ 101) unless there is a significant friction
- For that type of resource (talented programmers/mathematicians) the friction is very small
- Russia has bad regulation and bad business environment in general
- Specifically, very hard to get investments[1], and investors interests are poorly protected[2]
- Silicon Valley utilizes these resource much more effectively, so that even other places in the US - NYC/Boston/Chicago - could not compete effectively
- Also, managerial talent in Russia is concentrated on more profitable business, like participating in natural resource explorations or working for state-run monopolies - very profitable and risk free if you have the right connections
Disclaimer: I'm Russian living in Silicon Valley. That may have affected my judgement.
[1] I can share the following anecdote: When I was helping some friends to find VC funding in 2008 in Russia, I learnt that most VCs in Russia require kick-backs(!) from startups that they're investing in - presumably as a way to steal from their limited partners (and even provide some advice on how these kick-backs could be recorded in accounting books).
[2] Khodorkovsky's and Chichvarkin's examples are probably the most well-known on the West.
