I want the user experience to be stuck in 2095.
I want the user experience to be better than it is now.I'll give you an example of a web app that I like: github. It is built as a web app because it makes sense as a web app, it works really well, there's no cruft. It could be better if it were an API with user built clients, something git is designed for anyway, but it's not bad.
I would be fine theoretically with web apps, if there were some way to ensure actual web apps that need interactive functionality were the only ones that could use it. The situation we are in now every document is a web app, every piece of content you try to see online loads it's own application just to render. I have a video player on my machine, I shouldn't have to download and render a video player onto a one size fits all abstraction layer every time I want to play a video. I shouldn't have to download an entire rendering framework just to display a CNN article.
The right way to do the web is with APIs, client applications and protocols. If you're delivering a document, I should use a client applications to render documents, which is what browsers are supposed to be. If you're building an interactive service, give your community an API to build a client or build a client yourself. An instant messaging application should not be rendered in a document delivery program delivered over HTTP. If there's some use case that requires a standard, a standalone application that implements that standard is the way to go. Think XMPP and pidgin. How terrible would it have been if XMPP could only be used in a web app?
These design decisions are not about the user, they're deliberately designed badly because incentives are misaligned. Can't find what the user bought on the internet and sell that info to marketing companies if you just deliver content and let the user choose what software they execute.
The future is what I'm looking at, not the past. To deliver a truly useful web you have to determine it's shortcomings and rethink the architecture that led to those shortcomings. Saying "this was a bad design decision and look at where it led us" is not the same as saying "let's go back to 1995."
