It's amazing how much you can learn in your free time, to get a taste of a new field. I've watched some lectures on type theory. Which is super hard, and I didn't understand most of it but it gave me a flavour. I attended meetups on compiler design, spent a few hours on machine learning courses online. Most of these things gave me a flavour of that field but no expertise of course. I've settled on Elm development as something I am passionate about for various reasons (wont go into here) and want to spend a lot more time on, so I am building a side project that could become commercial in the future. So I found what works for me by experimenting in my spare time, but you only need a few hours to "spike" if you will like a topic. I guess it's a bit like the 'fail fast' approach used in start ups. For example I thought that I 'should' enjoy stats/machine learning but really I hate it. Someone else can do that thanks, glad I only spent 10 hours on it.
