Typescript will have no adoption problem. It is the defacto only compile to js language supported in NPM. It is also ergonomic to JS devs who want or are forced (at work) to use typing and an option on most scaffolding tools like NextJS or CRA. The fact that TS is actually very good just confounds this more!

It will live as long ad JS is popular. The main threat is web assembly which will make JS compatibility seem quaint.
