Except it is, as that is the single goal of this thread: Find out who is the longest serving Programmer, not the oldest guy doing something with IT. His remark is not wrong in that context.
In addition that unnecessary post asserted personal things not in evidence, giving the most uncharitable interpretation which is actually in direct violation of this site's standards and practices.
A question like "But have you been continuously employed as a programmer?" could be reasonable and not mean-spirited.
Definitely the comment was mean-spirited, but the core - which is that if we are trying to determine longest programmer, this is likely not a contender - seems to be true?
I don't think the OP is looking to claim the "Official Award for Longest-serving Programmer" as much as they are looking to start a discussion to learn more about others (which Ask HN is almost always for). This is an anonymous online forum after all, how much strict moderation and fact-checking of peoples history do you want to have?
If we want to play fast and loose with our definitions then I’m a farmer, because I grow plants in my backyard.
Even all that aside, his tone and dismissive attitude towards ageism is not welcome here.
Your gatekeeping is not welcome here. This isn't a competition.
"The reason you are able to completely ignore the age issue is because there's no ageism in hiring business analysts and project managers. The ageism is visible in hiring programmers, which most certainly you are not."
and your unfounded conclusions aren't welcome either.
