> people have accepted the poor experience of real time applications (client side crashes that bring down the entire page, half-baked routing that is essentially just rebuilding the browser navigator, inconsistent client vs server rendering processes).

People complain about that stuff all the time.

>stick their head in the sand when these issues are occurring. there's complete classes of problems that simply go away when you're not building an SPA.

Well, yes. If you don't actually build a real time application you won't get the benefits of a real time application.

>in the long run, yes, but in the short term you're probably not going to get your mvp out faster because you chose TS

Once there's even a moderate level of complexity (i.e. 2-5 devs for 1+ months) the type system helps you catch issues. Even if it only saves you one 4 hour debugging session you come out ahead.

That assumes you sit down and write out your MVP without any significant refactoring. If you do have to make changes then TS will save you significant time there.

It also assumes that you're not writing tests that duplicate what a type system does. If you do write those tests then again I think you're slower.

Rails does have the advantage of there generally being one "Rails way" of doing things. That can short circuit a lot of design discussions and other sorts of bikeshedding. But you can also just not do that and, IMHO, come out better.
