If all code was Typescript, maybe the author would have a sound point. Because of JavaScript (godblessit), there are many things that were written in a way that makes types difficult to implement. I work on Ember codebases and, while some of my colleagues who happen to work on Ember probably would disagree, there are things about the way it lazily resolves things makes it extremely difficult for everything to be typed properly without lots of recasting and bureaucracy that wouldn't have happened had the whole thing been written in Typescript from the very beginning. Typescript in Ember will always be a shitshow because of this design flaw that was encouraged by the era of JavaScript it was spawned from. Nevertheless, we shouldn't replace things that are otherwise working just fine, hence it's better to just accept that some things are going to be "any" or "unknown" and deal with them properly.
