Yes, he's also a software engineer[0]. Yes, I have a similar suspicion.
This is a longer topic, but in my mind there's a bimodal distribution on a spectrum of attitude towards programming. Some, like me, are people in love with technology, who go home to tinker on side projects. Other - like that cow-orker - treat software as a career, and they go home to socialize, play board games with friends, etc. Without judging anyone, my impression is that our industry is mostly filled with the second kind of people now[1], and they seem to predominantly feel good in open-space offices.
In the end, I figured that my preferences must be in minority, so I don't complain too much. That is, unless someone is really distracting me for longer periods of time, at which point I'll kindly ask them to stop.

[0] - I'm not here to tell him how he should feel about his degree. For myself, looking back at the education I got, I think my feelings were best expressed by a friend of mine: "if for that I'm an engineer, then I'm afraid to go to a doctor".
[1] - I believe it used to be different in the past, but that impression might be colored by small exposure to the real software world in my teens; the kind of people you meet on-line in programming circles are usually self-selected to be tech lovers / geeks.
