Do you see that as a maturation process? Is this about moving into management?
> Most degrees and professional certifications are meaningless to people who only care about the knowledge - there's no point in chasing paper that's out of date the minute the course is designed. We don't want that knowledge, it's old. We want current information which the courses and qualifications haven't been designed for yet.
A couple of additions or objections (depending on how some of those terms are understood):
If you care only about knowledge, then you don't care if it's the latest thing or has any application (though I rarely encounter knowledge that has no application). It you care about job skills, and about knowledge only to the extent it serves those skills, that's a different matter.
Also, you can learn about all those technologies, old and new and future ones too, by learning theory. Theory is the most applicable knowledge; it applies to and predicts everything - just like theories in physics predict how every object behaves, now and in the future, not just specific objects in specific contexts. Theory empowers you to solve novel problems and learn the novel tech.
Generally, I think the best way to learn knowledge, including theory, are good degreed programs: They are designed by experts (how do you design a course of study for a subject you don't know?), you have experts guiding and coaching and mentoring you along the way, and you have access to assets from labs to libraries to peers.
