I am of similar age and I've been betting on a combination of broad experience and productivity. Knowing basics of everything, but being really good at one thing (atm AWS and serverless), and applying latest productivity techniques to get things done efficiently (atm GitHub Copilot, ChatGPT, etc). So far I've had lots of work available. I'm expecting that the "really good at one thing" will change in the upcoming decades, and that you need to be early in learning it to stay relevant. I put some effort in learning decentralized Web3 in case that would be the big thing, but currently it's not it. Trying to keep eyes open for what AI brings up next.
