I'm a developer and am currently 47 (about to be 48). I'm the youngest developer in my department (basically call processing) where we work with C, C++ and Lua (which I introduced into the company). Down the hall is another department writing software to be embedded in Android phones (Java, obviously). With one exception (I think he's 30 ... maybe) the average age is mid-50s. The department working on the UI (HTML, CSS and Javascript) are in their 40s, like the department working on the (non-call processing) servers (Java mostly).
