Perhaps he's able to produce great stuff like this because he has a normal job in a normal company.

It isn't so much the "normal" company thing, I think, as having a good work/playthings/life balance. The main reason none of my personal/toy/experimental projects are languishing on note paper or electronic equivalent is that my balance is very wrong and getting worse!

He is presumably working for a good company (or at least one that is good for him) and has time management skills himself.

That, and a brain to be envious of plus a supply of inspiration!

I would think he'd be a patent office clerk...

But do you think he'd be passed over for promotion until he 'fully mastered machine technology'?

Judging from his performance review, there's definitely room for improvement :)
