Yes, statistically IMO most of those in the “traditional software development background” group are those from the not-so-young group; because traditional software development was the only branch in programming and design in their time … unlike now where we have web and games etc – but also because the modern generation has less training all round. Less people with tertiary education, people doing lateral movements in organisations and government into roles they have little experience in, which does bias the trad. s/w dev group make-up.

But again, I agree, not age but background and experience.
