I think this begins to be visible even sooner, 38 if you graduated at 23. The majority of the job market requires very very few 15+ years experienced engineers. 5 to 10 years of experience is a sweet spot - you will be easily hired. Everything below and beyond is a struggle, especially for the latter since very few companies need and are willing to pay for those skills.
And that's how you become unemployable with the irony of being at more or less what would be the peak of your technical capabilities. In years later on, people start to lose the drive.
I'm very good in my niche, but businesses just want 'answer to question'. I can provide 'answer to question while also making sure the answer-generating process is fully reproducible, data limitations are addressed and made visible, uncertainty has been calculated and is included in the answer'.
Not every question needs that!
Most people are willing to pay for Ikea furniture, not hand-crafted artisanal pieces. Ikea is good enough.
On the other hand, I just got hired at 55 and it wasn't difficult.
The baseline requirement of technical competence for extreme financial success in tech is so low that most big tech companies don't even hire rank-and-file engineers whom don't meet that requirement half-way.
that is, a 50 year old isn't even asked what their salary expectations are, it is simply assumed to be higher than what they want to pay, or rather, they can't bring themselves to pay someone like that less than they think is appropriate for their age. combine that with the perception that older people are less flexible and unwilling/unable to learn new stuff, and you end up with the belief that older people are expensive and useless or overqualified.
And as time marches on, there’s more and more competition for those roles.
- Minor health issues accumulate and become a distraction. Especially insomnia.
- Having worked on many projects and technologies that went nowhere, my enthusiasm for the work is diminished, making me less focused.
I decided to return to the last work that I found meaningful, which was as a software developer in the U.S. civil service.
I think this was the right move, although Trump and Musk are doing their very best to make me question that.
How about an angel investing firm for 40+ founders only?
