I think the comments in this thread captures it pretty well. If someone doesn't see the benefits of typed languages, TypeScript will just be something that slows them down for no apparent reason.

Same goes with RxJs, dependency injection, unit testing, and modules.

But Typescript is not a "typed language", rather a "language with types". Because of having to maintain JS compatibility it lacks the inherent type safety that other similar languages like Dart provide.
