I am 50 and I do OK. I also see people around my age and older who do well too. It seems to me that a lot of people who get filtered out in their 30s should never have been in the profession either for lack of motivation, interest or talent. If you are not self motivated to constantly evolve you have a problem. Moreso than in a lot of other professions.
"If you are not self motivated to constantly evolve you have a problem. Moreso than in a lot of other professions." I was self-motivated to constantly learn, and had no trouble doing it... when I was young. It was the right profession for me then, when I had the interest and passion. After a while, though, much of it starts to seem the same. The towering vistas that were once full of mystery, adventure, and discovery…
I took my current job with the goal of transitioning into a leadership role, either product or management. I was walking into a situation where I knew people already here and was hoping to leverage that. Those people left a few months after I started, and now I'm kind of stuck on an island. I've approached my current boss but he's completely uninterested in promoting any sort of career development.
Bottom line is I'm burnt out, depressed, and bored out of my mind. The idea of learning Yet Another Web Framework fills me with dread (I'm currently doing Node/React stuff and hating it), not because I don't think I can learn the tech, but because it's no longer fulfilling in any kind of personal or professional sense.
So, I really don't know where I'm going, or what I'm going to be when I grow up.
