> We have studies showing how different software engineering is, where some workers vastly outperform others, some workers are interchangeable, some are specialists, and some underperform. Do we? Please, show these studies. Obviously, we can only accept peer-reviewed replicated studies. Not some study which was never replicated (there are a few) or even worse some blog post by someone stating they personally know 10x engineers or whatever.
