I know the Birth and death of JS gets mentioned quite a lot in WASM context (even as a joke) but I really don't see that being the case. Most web applications/sites are simple, and won't need to be compiled at a lower level in order to work. On average JS developers will be cheaper than C/C++/Rust developers to hire, so I don't see shops changing their personnel or stack anytime soon, especially if the job is to knock up a website that's a bit interactive.

It simply won't be viable to have low-level engineers do things like "build a dropdown nav" or "make an interactive carousel", and these sort of tasks will always be around.

WASM is there to augment JS in places JS isn't suitable for, rather than outright replace it. JS will definitely still exist.
