I don't know why anyone down voted this because there's definitely at least some truth here. A lot of times the stereotypical 10x rock stars in an organization are really smart and productive people who ship features and move on to the next feature, leaving maintenance to the people who are left behind. They get the glory, but in many cases (totally anecdotal of course) they did it by taking all sorts of shortcuts and kludging things together in ways that aren't scalable or maintainable.

In this case, the 10x productivity boost comes from incurring technical debt that they personally will never have to deal with. Many organizations need these people in order to actually ship stuff, but their productivity comes at a cost that's paid for later, by other people. Maybe they're 10x up front, but it ends up being more like 1-2x when these costs are taken into account.

I'm more worried about the much more tangible 0.1x (or the feared but very real -1x) engineers, who exist in many organizations.
