A lot of organizational problems all reduce to ego. The second you have someone on your team that isn’t empathetic or humble, it tends to lead to major problems.
I’d take someone that’s not that good at their job but has a lot of humility and is willing to learn over arrogant masters (arrogance is the sign of a false master) pretty much any day. The single exception is probably cases where stuff really does just need to happen and happen quickly without mistakes, but ideally you’re managing projects in such a way that you’re not in that situation to begin with (though of course it can happen).
