This is the real advice at the very end: "But the best way to have a future is to be part of a team that values progress over politics, ideas over territory, and initiative over decorum."

The story is cut short though, and he doesn't really provide any evidence to back up that advice. Did the company that favored politics go out of business. Do company that favor ideas over territory consistently work out better? I think, as engineers, we'd like to believe so, but I'm not sure that's what I've seen from my own experience.
