In-between coding there is more human interaction and the craft of coding itself became more social on an abstract level (code should be more communicative and all).

But I would still say it is far from really social jobs - after school, I worked at a home for elderly people, and everyday left me exhausted. After work as a programmer, my social batteries feel much more charged.

One could make programming an extremely social endeavour though, i.e. by constant pair programming (two of Googles best Software Engineers are doing this).
