Wrong? You are comparing number of possible values that can be stored not the amount of bits. Drive sizes are specified in bytes not possible combinations it can store.
I would much rather see web apps become canvas rendered WASM versions of desktop apps than desktop apps become webview apps. Latter is what we have been seeing in the recent years unfortunately.
Canvas rendered cross-platform UI frameworks like Flutter & Avalonia targeting browsers (WASM), might shift the balance back in favor of desktop UI.
