Sure, we can ad hominem this all day. I suppose it's entirely possible the reason that in team after team over 20 years, the reason it's always a small number of engineers who get the most done, by a very wide margin, that the problem all along was me. This despite the fact that I consistently see the same gap in teams I don't manage -- where every project has a small handful of standout engineers responsible for most of the codebase, and then a whole bunch of people who inch along. But what's your own experience been? Have your own teams been absolutely full of high-productivity developers, everyone contribute roughly the same amount?
