You've moved the goalposts. Neither ancestor comments nor the article were talking about founding a startup. But having conceded that programmers who start late are not necessarily at a disadvantage in terms of technical skill, you've changed the question to whether programmers are "fine and capable employees" or "more than that," apparently meaning success in the tech industry as a startup founder.

Younger people have advantages entrepreneurially speaking. But we shouldn't mistake that for technical skill by redefining hacking as "being a technical startup founder."
