I’m mid 40s and took the other route. I was self-taught and decide long ago that I never wanted to manage other people. So instead now I run a small solo audio company. Never have to deal with anyone but my own customers. I consider it a craft not a startup.
It isn’t for everyone but whatever LLMs end up being for us all, in this position they seem more likely to be an asset than a liability. If they are good enough to replace me then they can be my army.
