Totally agree; I'm now very similar to your example, only I came from being one "the" 10x-er. Then I worked with another 10x-er at the same time as we had our first kid. With no sleep and no time to learn I could remain a 10x-er so transitioned into a Tech Lead (and am now moving towards CTO).

Now I spent my time optimising/running the system of software creation and delivery, being the face and the glue - because hey, that's me.
