Whenever AI is mentioned lots of people in the Linux space immediately react negatively. Creators like TheLinuxExperiment on YouTube always feel the need to add a disclaimer that "some people think AI is problematic" or something along those lines if an AI topic is discussed. I get that AI has many problems but at the same time the potential it has is immense, especially as an assistant on personal computers (just look at what "Apple Intelligence" seems to be capable of.) Gnome and other desktops need to start working on integrating FOSS AI models so that we don't become obsolete. Using an AI-less desktop may be akin to hand copying books after the printing press revolution. If you think of specific problems it is better to point them out and try think of solutions, not reject the technology as a whole.
TLDR: A lot of ludite sentiments around AI in Linux community.
Yeah, on that I'm gonna say it's unnecessary. I don't know what "integration with the desktop" gets you that you can't get from having a web app open or a separate window open. If you need some multimodal goodness you can just take a screenshot and paste it in.
I'd be more concerned about model performance and having a well integrated multimodal assistant that can do image generation, image analysis and text all at once. We have individual models but nothing like that that is open and free, that I know of.
