I'm 41 and I still don't feel old even though I work with a few people who are 10-15 younger than me.

We tend to think of old programmers as these ancient neckbeards who write COBOL and FORTRAN and grew up on usenet programming PDP machines; but the reality is that 40+ year old programmers today were kids in the 90s, were in their 20s when languages like JS, Python and PHP became popular, and played quake 3 in their early twenties.

BTW I'm not doing straight-up programmer work, more of senior architect type roles in the past years, so it might be more "acceptable" in the industry to still be spending time with an IDE at my age in this context.

It's not, but he has to call himself old to give his business idea credibility. (which I think is fair, by the way)

I dont think its as much a business-motivated thought, as it is an observation about there being a very distorted age spectrum associated with working in tech-related industries.
