Most 10x engineers I've met are usually very creative and care deeply about the user experience and keeping code maintainable over time. Most 1x developers just care about getting the job done regardless of care or code quality, which in my experience has led to conflict.
I've rarely seen those 10x engineers to bring massive long term added value. Most are/were well aware of their skills and detested working on anything but newest and shiniest, desperately trying to make work a fun park for them regardless whether its actually a good idea for the company giving them paychecks. Which works for some time, or when extensively coached, but eventually they move since their time is oh so pr…
I've seen it first-hand. We ended up building a support team around the 10x:er to keep things working, but it was easily worth it. It worked very well for the life span of the product - about a decade.
Many eventually graduated to pretty fancy places. They learned a lot. This particular 10x:er loved sharing knowledge via pair-programming.
Well, he was always in command of the keyboard (typing insanely fast), but you'd sit next to him and he'd delight in explaining. Eventually you would challenge him on something and then the collaboration/adventure began.
I have had the most intellectually exhilarating times of my life working with this guy.
So yeah, 10x:ers can bring massive value if they are wired to be really nice.
