Sorry. But that is precisely the point of opportunity costs.

Building that reactor isn't just a job. That kind of a job generally has a future/career. You would learn so many things on the way you will likely land a better job sooner or later.

One of things that I keep saying to my younger cousins that pretty much everything I built at the start of my career in programming doesn't exist now.

All that remains is me, and along the way I've gathered skills.

Video games don't give you this.
