Where would that lead?

That's the billion dollar question. Whoever figures that out and builds it will be the next Microsoft/Google/Apple/...

Microsoft, Adobe and a lot of other companies are starting to patch some AI features into their apps, but the thing that makes ChatGPT so interesting is that it is universal, it can generate code, cooking recipes and write short stories and it can do all of that at once. Having an AI be stuck in a single app feels limited compared to that. But at the same time ChatGPT itself is locked in its own little text-window, which is limiting it as well. ChatGPT-style AI that can operate like a full OS, that would be the holly grail and I am sure plenty of companies are working on something like that.

Not sure about blog, but here are a couple of random vaguely related books and videos on the topic:

• The Design of Everyday Things
• The Human Interface - this is about the concepts later used in Archy
• Steve Jobs NextStep tour
• Zoomable Interfaces
• Eagle Mode - Zoomable Interface Software
• The Mother of All Demos, presented by Douglas Engelbart (1968)
• Ivan Sutherland Sketchpad Demo 1963
• Alan Kay: Doing with Images Makes Symbols
• Ted Nelson demonstrates Xanadu Space
• XMLTerm - XML based terminal
• VR Interface Design Manifesto (2014)

I find the older stuff especially interesting as it has a more clean-slate approach to interface design and isn't stuck in modern conventions.
