>> What are some things that only someone who has been programming 20 years knows?

Those in positions of power (the managers) have never been those who programmed 20 years. Either never programmed at all, or were early successes either trough luck or more often than not, connections.

As a result they don't know and don't care about the things known by those who programmed 20 years, it's not their problem.

That's simply not true! I'm 43, and there hasn't been a day without coding since I got my first computer 32 years ago. I'm also managing teams for the last 20 odd years; small teams, large teams, in startups and large corporations. And I know many others like me.

The same here; 43, daily coding since I got my first computer beginning of the 80s and managed companies and teams for well over 20 years.

I'm going to (somewhat) side with the other guy and say that you're the exception, not the rule.
