I'm not interested in learning iOS or Android or other native GUI programming (but will if I have to).
There are other things that I'm interested in for curiosity's sake, but would probably be a waste of time in the short term for my career path, like assembly language, AI/machine learning, connectome simulation. I do want to learn more math, now that I've become unsatisfied with popular explanations of modern physics, but it would be a distraction as far as my career is concerned to spend time on it.

We strive for transparency and don't collect excess data.
