Of course, there's more than one way to build a good product.

Personally speaking, I'd say that adding another layer of abstraction onto your stack shouldn't be a dogmatic thing that you just reflexively do without considering the actual needs of a particular project. TypeScript offers some benefits for certain types of complex projects, but also some costs and problems that might not be worth dealing with for certain projects.

It's a little bit like GraphQL in a sense. That's a phenomenal idea...for a product like Facebook...but probably not actually needed for every single project.
