When I watch a talk like this, I am startled by all the complexity and syntax added to languages to hide some implementation details or allow you to write one function instead of several or whatever else. Everything has its use case, but generally I feel it's insane. Devs are forever learning the new hotness for a marginal benefit. Nobody ever masters their tools. https://m.youtube.com/watch?v=BbfBJv0iXm8
