I feel like this article completely misunderstands the point. Their two big arguments are that 1) people aren't 10X at everything, they are at most 10X at specific things and 2) what good is a 10X engineer if they are on a team that can't perform at that level? There isn't something magical about 10X engineers, but the fact is there are engineers who have developed the skills to greatly exceed their peers and work in those sub disciplines at which they have this skill. Who cares if your 10X mobile app engineer would be no better than anyone else at microprocessors, they aren't working on microprocessors. Likely anyone could become a 10X engineer, but most don't. It's like great athletes or great musicians - whom no one would question are 10X better than average even if quantifying skill in those domains is hard - maybe there is some level of god given talent but for the most part it's years of effort that other people just don't put in. Then yes, engineering is often a group effort and a bad team can certainly hold someone back, but just as in sports a strong player can certainly elevate an otherwise mediocre team particularly if well utilized, a 10X engineer can massively improve the output of those around them. No one on earth would say it doesn't matter if our band had a great cellist because the rest of the orchestra probably isn't exceptional. If a team holds its high performers back, that's a problem with the team, not a limitation of high performance.
