Wasm is slow with strings because the MVP doesn't support strings. Once it does the performance bench marks will change in favour of wasm.

JavaScript is the new cobol because developers want to program in a single language. As soon as wasm supports a wide variety of languages the long slow death of JavaScript will begin.

JavaScript is more like the new Visual Basic For Applications, you have to use it because is the only option.
When other options appear, some developers will stay with js, some others will innovate applying more robust technology to the web.
Nothing that have not happenned before.

I don't think that is the case. Currently a lot of people enjoy writing JavaScript, which wasn't always the case.
Of course people enjoy it, they actually enjoy it too much.
