"Clean Code"? Why? So someone else can take over this codebase after I get laid off? Hard pass.
We're going to see a major increase in code silos, code that is difficult to read, land-grabs, and people being protective of what they build. Whatever people have to do to become costly to lose, that's what we're going to see.
If you make someone's paycheck depend on their ability to prevent someone else from taking over their code, that's what is going to happen.
