Seems like you're confusing a number of things here. Progressive web apps can be cached offline and load instantly. They typically have smaller download sizes than native apps. There's zero reason for a PWA to take longer to load than a web page because a PWA is a web page. Perhaps your complaint is with Single Page Apps? That's a legitimate complaint, but doesn't really have a lot to do with PWAs.

Users don't know what "responsive design is". But conversion stats for sites that have a specific mobile layout vs ones where you're pinch-and-zooming constantly show that users are a lot more productive on sites with a mobile view.
