This reflects humans. If you need reliability for a clearly defined set of problems you don’t hire a superstar.
They will keep poking at the problem, drive it to directions you did not intend to and ultimately they will be worse at the task.
I’m not sure that’s true. In general, the higher the performer the better they’ll do. That’s the definition of high performer.
Reminiscent of Kobayashi Maru. You probably don’t want the James T. Kirk AI. ;)
