I actually think there’s optimum voluntary and non artificial turnover where people naturally move to other opportunities. And conversely a calcification where people get stuck in a comfort zone.

I don’t think people should be forced to leave. Instead I paradoxically think people should be hired more interested in growth and this more likely to leave / move around the company / try different roles.

Who defines calcification and comfort zone? Be careful you don't confuse a mature stack with subject matter experts who can execute effectively as "outdated calcification". I would be wary of someone who wants to hop around a lot. Are they adding tangible value to every team or disrupting things before bailing to the next team?
