Definitely. You're not wrong. But one of the downsides of sticking around for 4+ years is, like I said, there is a _risk of_ (ie, not guaranteed) becoming kind of a stick in the mud and the company then could suffer from your leadership/clout rather than benefiting from it. I've worked at several companies where the leadership had been there for 8+ years, and that led to inertia and small-C conservatism and reluctance to adopt new technologies or paradigms that would really accelerate company growth. The companies were generally successful, but working there was kind of a slog and it was tough to attract new engineers to work on old tech in outdated paradigms. That said, there are plenty of folks who _like_ the old tech, so it's not necessarily a deal-breaker for anyone.
All that to say: you aren't wrong. If you're in that position and you don't want to leave, that's really the company's problem and not yours. Do your own thing! I support it 100%! (Not that you need my support, but you have it anyway!)
