I build a PWA currently in use by around 130 people, no one can tell its not native.
Because when you compare native/PWA with mainstream apps the experience is significant.
Yes, I can speak for them. They compared their native implementation with the one that exists. The users enjoy using the web app compared to the current native app.
Why? Because it doesn't exist. Because creating a native app doesn't solve the problem. Because when you say "native", do you mean iOS or Android? Or Mac? Or Windows? Or Linux? Or whatever else there is?
Yes, eventually, there might be a desire to build out a native app if it's needed. But the assumption that everyone needs a native app is absurd. Not everything needs a native app, and can work just fine without.
As for this persons users? Yes, they enjoy the PWA, because without it, the "native" app wouldn't work for some of them.
But if you think it will upend the industry then that is frankly delusional. PWA apps are worse than native in every single way for the user. Great for developers. Terrible for users.
And as users can't tell, why is it terrible for users? All kinds of apps can suck and be user unfriendly. That's a different dimension than native vs web.
That's the whole reason for why the last 15 years of trying web based apps have failed.
