10x engineers thing is a lot lot simpler than that. In vast majority of cases, it's just one normal engineer surrounded by a crowd of people who should have been flipping burgers, but ended up working as 0.1x engineers because of "talent shortage" which is in fact just some bosses being too greedy to pay normal wages. Over time, abysmal productivity and quality of their work becomes the norm, and one normal guy who randomly happened to be there is seen as a semi-deity.
