There's also a large number of folks moving to management as they age. Yes, the tech industry tends to skew young for engineering, but management doesn't. There's also a relatively decent chunk of people retiring in their early 50s (I plan to). There's also a decent number of them leaving to create their own companies, or to join friends at their early stage startups.
I don't think it makes sense to say they're the exception. I'm also mid-40s and have no issues finding employment. Most of my friends are mid 40s/50s and also have no issues. The vast majority of them have switched into management, though. Myself and the other older engineers I know are staff+, though, which helps a lot. I can't imagine being this age as a senior engineer trying to fight an army of equally qualified people in their 20s (who are also having issues finding employment right now).
The HN bubble is real. Most developers are boring old enterprise developers who toil away at writing LOB apps spending their entire career in corp dev if they don’t move onto management.
They live in second tier cities and retire at the same time everyone else retires.
If you are 40 years old and still competing with 20 something’s based on your ability to reverse a b tree on the whiteboard, you have made some poor life choices.
