There are also 100x engineers and probably even some 1000x+ engineers.

These are the kind of people who cook up something like git when they take a one year sabbatical from their main project.

Or even hardware people like Jim Keller.

10x engineers are plentiful if you define the median engineer as 1x. There are a LOT of mediocre engineers out there to draw the median down.
