I can also do programming things in 1x which friends who fiddle with Arduinos can't do in 10x the time. But they are non-professionals, and may even stuggle with fizzbuzz.

But in a professional setting I've yet to meet a single developer I would claim to 10x. Probably not even 5x. Unless one would look isolated at tasks that requires specialized or domain knowledge which the other person doesn't happen to have. And I'm pretty sure there would be tasks where same person would nX me.
