I'm also in my early 20s. I'm personally aiming for being very good at a few things with a lot of very high level background knowledge. Basically an extreme T-shape. 1) I believe that not having a clear competency will make it harder for people to place you. Your experience is a lot more legible if you're the "React guy", "C guy", "AI guy", etc. 2) Trying a bit of everything is very different from being good at everything. Is "a bit of x" useful? From what I've seen, no. It's not a unique differentiator, it's easily replicable and it doesn't provide much value. Being good at a few different things seems like a different ballgame though. 3) If you are a very broad generalist it will close a lot of doors for particular work. If you are highly specialized it will close a lot of doors for particular work as well. AI/ML for instance, seems like the kind of field that will be closed to you unless you specialize in it. On the other hand, building full products is something that seems more inaccessible to specialists.
