I understand where you're coming from -- there are some truly good engineers out there.

But I think he's right too. He's essentially arguing about the true meaning of the metric. Of course there are engineers who can spot bugs at 1/100th the time as an arbitrary engineer. Or fixes things 10x faster (being familiar with the code base certainly helps).

But to have the literal productive capacity of 10 people? That's much different, and that's what he means. Are you capable of replacing 10 arbitrary engineers with the rockstar? No? Then that's not a 10x engineer, by his definition.

It's rare that anyone tries to replace 10 ordinary engineers with one 10xer. It's common, however, to try to replace one 10xer with 10 ordinary engineers, and find that they can't cope with the challenges.
