There's 2 big ones that I want to learn. Quantum computer programming. I've dived a couple times into Qiskit from IBM. Also tried to get into dwave and ocean sdk but they never got back to me. Qiskit tutorials are easy to blow through and i think even understand. But when trying to use it for my own purposes, just never get anywhere. The other one for me with no success. Training my own specialized predicting AI mode…
My concern with quantum computing is there's already such an outrageous overabundance of quantum computing PhD's the marked will likely be saturated for decades to come. It would be a ton of fun to learn, but I can't justify the time because there's no career progression
Now whether it's worth learning? Eh, maybe it's good to exercise some math skills that have been atrophying.
