There isn't anything actually wrong with JavaScript in 2023, either. The idea that it needs to be replaced stems from countless failed attempts to shove a bunch of crap into the client with a bunch of frameworks and without a shred of actual engineering discipline. Trust me when I say that, if web apps become commonly written mainly in other "scalable" or "type-safe" languages, your average software developers will find a way to screw that up as much as they have with today's web, if not worse than that.
WASM is cool, but I don't see any reason to get rid of JS. There's value to having a lingua franca of JIT interpreted code with a standard UI toolkit, and I think those who point out how "insufficient" the DOM is and how "slow" and "unsafe" JavaScript is are simply wrong. They both do their jobs exceedingly well when idiotic and theological ideas are not simply thrown at them by software developers obsessed by convenience over soundness of design.
