I specifically said anecdotlly. Your experience and my experience a not representative of anything. Also that is only a small portion of my comment and was meant more a a sidenote.
We were also not talking about windowed mode at all here. It was specifically about what happens when you press the green window control button, which as far as I know puts the app in fullscreen on macos and the equivalent on any other OS known to me is to maximize the window.
Using “AI” has been beneficial for example to generate image descriptions automatically, which were then used as alternative text on a website. This increased accessibility AND users were able to use full text search on these descriptions to find images faster. Same goes for stuff like classification of images, video and audio. I know of some applications in agriculture where object detection and classification etc. is used to optimize the usage of fertilizer and pesticides reducing costs and reducing environmental impact they cause. There are ofcourse many more examples like these but the point should be clear.
