Nice wrapup ! Typescript fan over here but it is interesting to confront different opinions.

As for me, I consider typescript as a standardized way to give my IDE the information on my code.

As a library author in my company, I use typescript heavily in reusable code to give my collegues a "dropdown-driven development" experience. My goal is to make my peers more efficient and some advanced types help to deliver auto-completable, auto-validated libraries.

Coupled with a strong testing strategy, I found it very useful for refactoring.

Typescript take the direction to understand better and better javascript as well, so I suspect that at some point, typescript will be the inference engine for javascript ever and everyone will benefit from it.
