Sadly, even if "veterans" like Dorsey, Page, Brin were to run for federal office, they would be amongst the youngest to serve.
Even if you arbitrarily want to restrict your scope to Googlers: Peter Norvig, Rob Pike, and Ken Thompson are decent examples of veteran technologists who've seen a few changes of both technical and business environments, and have some basis for comparison. Brin, Zuckerberg, and Page don't really have that kind of experience.
I was more or less trying to draw the distinction that in some fields, sports, entertainment, and at least some technology enterprises youth wins out. Recently it was determined that by industry, technology is one of the "youngest" industries with an average ago of 30. That puts tech close to retail and food service.
I think it was Forbes, I can't find the link though.
