Would be amazing to see someone who is really good at software development doing something cool like that.
Why is in inexcusable ? I wont mind if my employee does it. A lot of smart programmers finished their job in 4 hours and went home early. Got pay raises too.
However, I see someone sitting back for six years without offering any input on improvements or anything, just literally collecting a cheque and doing nothing as not being efficient or showing motivation for the company.
I agree, it shows he's smart, though he doesn't show commitment in my opinion, which is why I wouldn't justify a promotion. That's just my thoughts on the matter.
It's pretty clear management at that company is woeful if it is possible to automate all your work on a damn software project. Woeful management embarrassed by it and busts out the fire-hammer. Who are they? Short them?
