I think you're misunderstanding what he meant. At least, it seems that what you got out of what he said isn't what I did. When he said 'quality', I didn't think he was talking about people as "mates" or as gene quality or some such. I took 'quality' to mean exactly what you want it to mean - attractiveness, how much fun they are to be around, etc etc. Basically, whatever you would look for in a 'significant other' - certainly not just gene quality or whatever.

As for the tone, it is a bit unusual, I guess. Our crowd - hackers, programmers, engineers, nerds, whatever you want to call them - does tend to like abstracting things away, trying to model life that goes on around us in a precise and systematic way. The tone is due just to that.
