Let's pretend this is a journal article, if he pointed out flaws but didn't really do much else, does he end up in the list of authors at the beginning of the paper or does he end up as a thank you at the end? It seems in this case people like Jobs end up as first author. The rest is irrelevant. There might be several scientists far better than me, all that matters is that I got there first. My manager could also be irrelevant as I've had technically capable managers that didn't truly do anything except put me on a project, that they hadn't known beforehand if it was even possible to do, and tell me to do it with next to zero feedback throughout the entire process.
