Yeah, that's more what I'm getting at. I don't like straight knee jerk conservatism, but sometimes it is a useful instinct and it warns us to count the costs.
It's a bit like doing rewrites of major production systems. Not a good idea. But of course it's much worse because human culture is more complex than a computer program.
But also like major production systems, we definitely can improve them. Now we just need unit tests for cultures to make refactoring easier.
PS Have you read any Edmund Burke? Got an opinion of him?
