He doesn't have our bagage. He doesn't feel the anxiety the purists feel.
He just pipes all errors right back in his task flow. He does period refactoring. He tests everything and also refactors the tests. He does automated penetration testing.
There are great tools for everything he does and they are improving at breakneck speeds.
He creates stuff that is levels above what I ever made and I spent years building it.
I accepted months ago: adapt or die.
