"rock solid, snappy apps"
Where were those apps even before AI came along? Every piece of software I use in my day across Windows and iOS is a slow, laggy, piece of resource hogging garbage, and that was true long before AI came along. I'm not convinced that AI makes this worse, it might make it much better.
We used to have them—in the 2000s and before. These days not so much, but there appears to be a correlation between the push to use LLMs and a hockey stick in the enshittification curve.
i used a ton of good apps on windows xp and 7 (sumatrapdf, codeblocks, notepad++,…), macos (things, bear.app, cleanshot,…) and Linux. But that was a bit before SaaS and their electron clients. Now I still maintain a lean desktop, but it’s mostly standalone software with no reliance on the “cloud”.
