I think in fine the PWA problem stems from a lack of education: some developers were exposed only to Javascript and think of it at the alpha and omega of programming. Ironically the web isn't even a platform for developing software to begin with. And because they can't be bothered to even try any other programming toolkit, they want everything else to come in the browser (GPU, SQL, USB, etc), duplicating existing OS functions in a weird half-assed, incomplete, buggy and security-wise questionable way. I don't know what the fix for that is, but probably taking what pure web developers say less seriously would be a good start (in this thread for example, the reference to NPM, a package manager known for the vulnerabilities it enable, is laughable).

Just want to point out for appreciation: Using in fine in an English sentence is fantastic and not done enough.
