> learning to manage software projects gets you an almost unfair advantage at managing "simpler" and more mundane projects

I'd add that learning to write software also gives you an unfair advantage in managing the "complexities" of all other processes you'll encounter in day-to-day life, to the degree that it's (at least for me) incredibly frustrating going through life seeing inefficiencies and "incompetence" (not meant as an insult) everywhere around you.
