wasm isn't meant to supersede html/css/js (unfortunately) and it's regularly used for high performance applications in the browser, web-based cad software, figma, youtube (i think they use wasm for codec fallback when support is spotty) etc

there is also games, stuff to do with video (ffmpeg built for wasm), ml applications (mlc), in fact it's currently impossible to use wasm w/o js to load the wasm binary

as a result, the web stack is a bit upside down now, w/o the seemingly "low level" and "high performance" parts over the slow bits (javascript)
