I'm in my 30ties and after reading Harari idea of the future https://www.wired.co.uk/article/yuval-noah-harari-extract-21-lessons-for-the-21st-century I have started thinking about what would make sense to learn now that even if made obsolete in 2050 would help me along the way.
Any Ideas of that's worth learning in the time scale of 10, 20 and 30 years? I'm aware that even 10year scale is guessing - I'm asking to broaden the scope of things to consider and maybe try to look for any recurring answers.
