> Sure, that does make things easier: one of the reasons Go took so long to solve is that one cannot define an objective score for Go beyond the end result being a boolean win or loose.

Winning or losing a Go game is a much shorter term objective than making or losing money at a job.

No, not that are shorter term than winning or losing a Go game. A game of Go is very short, much much shorter than the time it takes for a human to get fired for incompetence.
