@matigo We have such a diversity of systems, versions and platforms in place that someone without 30+ years of experience simply couldn't "grok" them all.
We go all the way back to 1979
People who can hit the ground running with that cost far more money than we have to pay.
This means I have to be there and also intensively train which is something I can ill afford to do time-wise.
I'm trying to get things current to the point a fresh grad can handle most things and leave me for the things they won't be able to handle but it takes time. Especially when my attention is drawn more to day-to-day things than hard coding.
It's quite the pickle.
