I actually do think generating UI has some future, but I remain sceptical it can realistically go as far as promoters claim. It is especially bizarre to me when this is done by ostensibly UX people.
What I actually doubt is that people as whole are this adaptable to continuous novelty, especially when it is not directed by them.
As a developer, it already feels like this with internal company tooling. Anything I have the source code to and a build pipeline setup for, I can just pop open a new tab and tell it what I want changed, and it just gets done for me.
Even my home assistant setup at home now, i hooked up codex to it via an MCP, and when we put out the blow up haloween lawn ornaments I was able to just pop open codex on my phone and tell it to throw together an automation to run them for me, and 5 minutes later it was done, with an override button on my dashboard. It's a shockingly nice workflow!
Wouldn't it be nice if you could just tell your app to reconfigure/rewrite itself to remove those "what the app will think I need at particular moment" features that you dislike? Maybe have it remove a bunch of the whitespace, getting rid of the lazy loading infinite scroll, whatever you want. It's the GPL dream, except you don't need any coding ability, just a subscription to a megacorp.
Agents cut through all that crap and allow me to make changes without learning a new overwrought configuration language that thrashes syntax every few months. The fact that it is open and fully modifiable redeems it, because I can ignore all the annoying parts while achieving what all that was envisioned to allow.
And I don't need to build or debug complex automations any more! I can just tell some AI to make it so it auto-locks the house door when my phone isn't tracked at home, but also to check the wifi and if there are people using the guest wifi then to instead send me a notification asking if I want to lock the house because guests might be there.
Just like Codex failed so would that.
