I'm in a similar boat. I appreciate static typing and although I don't have any strong objections to TypeScript purely as a language, I can't get past the way it's transpiled into a dynamically typed language with source maps... Seems like a hack.

It doesn't make sense; kind of like transpiling lower level assembly code into higher level C code. You could always argue that there is value in forcing arbitrary constraints onto developers but in the end, you need to ask the question "is it worth the complexity?"
