Martin from Wasp here -> you are right that we kind of went overly into DSL, we are actually switching it to TS at the moment (experimental version already out for some time but now making it the main way to use Wasp), but not because of the AI, instead because we found it was too hard to maintain and develop. We thought custom ergonomics of it will be worth it, but turned out we didn't get much on that side, while we lost a lot by not using existing ecosystem of well known language.

Btw, AI actually works great for it. I am sure part is that the Wasp's DSL exists for some time now, but it actually worked well for the very start, because the DSL was quite simple (similar to JSON) and AI knows how to generalize very well.

So I wouldn't discourage people from writing DSLs because of AI -> AI can understand them very well -> but for the reasons of missing out on all of the benefits of using a strong host language and doing it as an embedded DSL in it. If you are doing your own, completely standalone DSL, you will need to implement a compiler, editor extensions, LSP, maybe module system if you need it, maybe package system/manager if you need it, ... . Although when I think about it, that is also easier now with AI, than it was before! Hm yeah actually maybe custom DSLs are a good idea these days, with AI doing most of the job for you. I still wouldn't go back to custom DSL for Wasp however because biggest thing for us is probably familiarity -> custom DSL just scares people off.
