Yes, and guess where they learned it from? Regurgitation and handing in "something" on time can pretty easily get you a degree, even at a top tier school. That will get you further at most organizations than a resume with completed software projects and no college degree. Once you are in, it's easy to do enough to avoid getting fired. No one wants to take the blame for a bad hire.

After a few years, they're a mid-level engineer and maybe they make good looking diagrams. They answer all of their emails, they show up for the meetings that actual engineers don't want to attend. They have a purpose and fill a role, even if they still fundamentally don't understand what's going on.

No matter where you go, or how high up the chain you get, they will be on every team and in every meeting. What they lack in technical understanding they cover with political and social skills. Which also means they will be your management.
