> If you have less churn, you have better efficiency and perhaps can get more done with fewer engineers.

True. But the downside is groupthink. New hires bring new ideas, new perspectives, etc. Heck, even something as simple explaining X or Y during onboarding forces the "teacher" to rethinking and reinterpret.

No chun? No new blood. No new ideas.

I 100% agree. There is a balance and also different dynamics based on the trajectory of the company. When a company is growing, you could have new blood and old hats. When a company is shrinking, everything sucks.
