It would be interesting to have some statistical data on this question. There are plenty of anecdotal information either way: I'm 45 and doing quite well as a software developer. So, no, not a dead-end job for me. On the other hand, I see less and less software developers my age or older in my company and others around. So while I'm sure you will get a lot of anecdotal data in the comments, it would be great to get some actual statistically relevant data. Does anyone know any good source for this type of data?
