This is why the 10x is a unicorn. HN likes to shift the definition every time it's found to have some quality we don't like. In the real world there is a broad spectrum of devs and their capabilities. Each one has strengths, weaknesses, areas of expertise, and character flaws. You'll basically never find one that just blindly produces 10x the code of the rest of your team without some downside.

They are Unicorns but you know them when you see them. Cranking out code at high velocity that looks and feels right. When they don't know how to do something they actually research and look at the field. If no prior art exists at all (they frequently find themselves in this situation) they're already on their third iteration before anyone else has a prototype - even they can't get it perfect the very first time.

E.g. If they previously wrote compilers and you tasked them with graphics you'd see a book explaining affine transforms on their desk. Or parsing theory for the reverse transition.

A key part however is the ability to switch between fields. I've seen people I thought were 10x completely fail when tasked with something new.

I reckon that if there's such a thing as a 10x dev, they'd act as a force multiplier rather than a faster assembly line worker. Fixing architectural problems early raises the productivity of everyone who ever has to touch the code, as does setting up practises like code review and automated testing, and as does culling bad features early on.

I agree and it might not be possible to recognize such a person as a 10x dev.

Imo, the whole concept is idiotic and serves nothing.

Of course it is possible for one developer to be better then other, but it is not necessary fixed. It changes during lifetime of same person, depends on technology, experience, type of project and other factors.

Meanwhile the typical use is to look at some stereotype you have in head that has nothing to do with the project or position at question and then wonder why it did not worked out.
