I'm in the same range and I would have to say that most of the people who pop to mind (caveat--there's probably some selection bias) have done pretty well.

Among people from school who I've kept in touch with. One founded a significant company. Another is Chief Scientist of a large IT vendor. (And another was--retired now--Chief Scientist at a large consumer goods company.) A few are consultants of various types. One is still a game designer (though he actually started that after school; he was a civil engineer).

I also work with a fair number of people in the same general age range. I'm sure some percentage are still primarily coding although a lot are development managers of various sorts.

Personally I worked and a Mechanical engineer for a few years but I've done technical marketing of various sorts or strategic/marketing advisory work for most of my year. (I do some programming but strictly on the side.)
