I'm thinking about this. However, how unreasonable it really is to stay at a tech company for less than 8+ years? All my acquaintances in Silicon Valley, especially the most talented ones, never had a gig that lasted more than 2-3 years. Things always "happened" to them. Putting all my eggs in this basket for such a long time makes me a bit uncomfortable. By moving to Google-like, I would shake things a little bit more for my career and possibly chase some luck.
