From what I understand, they're divesting resources that aren't in Firefox or at least involved in a trustworthy/open source AI project.
I see a lot of people in this theead are upset at this, but I'm tentatively excited. If they can pull off a good AI engine, especially built into the browser, that would be nice. If it had offline capabilities, that would be amazing.
Even if they can pull off a good AI solution that's not built into Firefox but it's offline, I'd be really excited. I'm not crazy about having especially detailed and intimate information being thrown to some vendor out there, not knowing where it's going. Modern AI can do some amazing things, but a lot of them reserve the right to have a human read whatever you put in them and warn you about that. This is too limiting to me for my preferred use-cases.
One concern I have is that Firefox and its engine are one of the last non-chromium browser platforms that have a household name and are FOSS. So to me, that has to be the first goal to keep healthy. Maybe the AI thing will help in this respect
