DHH hates typescript
Also reading this from DHH about dropping Typescript from Turbo:
So farewell, TypeScript. May you bring much rigor and satisfaction to your tribe while letting the rest of us enjoy JavaScript in the glorious spirit it was originally designed: Free of strong typing.
On one hand, I've long been loathe to engage with strong typing. Because, you know, they're a drag and they can introduce a lot of paperwork.
On the other hand, I've found it a saving grace on a decent-sized team all banging on a big code base. Tests help, but types help too - especially when you have an IDE like VSCode doing relatively helpful things like intellisense.
Also, typescript allows for gradual typing. That makes it way less of a drag than like, say, Java back in the day.
I also find it super-ironic that I've been a part of enormous Rails projects increasingly adopting static types by way of Sorbet to wrangle some of the chaos - i.e. exactly the opposite direction DHH wants to pull
