That's interesting; I never felt that programming was an isolated job. The offices I worked at always had plenty of socialization, both in interaction for work purposes (with not just other programmers, but also other people on the company and even quite a few clients) and during breaks, lunches, post-work outings, etc.

I guess this might be different in a large org with impermeable "silos", where you just talk to your direct teammates and work comes in the form of tickets. I mostly worked in small companies (under 50 people), with little bureaucracy, and specialization is a little less strict.
