I'm mid thirties, went from full stack dev to DevOps to sre. No real regrets on not specializing in a field, however I do wish I had spent more time contributing to some specific open source project that's heavily used. I think generalist knowledge + in depth knowledge of some widely used codebase would be a bit more lucrative.
