For what it's worth... I think there are useful AI tools. For example the offline translation feature that doesn't send your content to google is something they recently introduced. I'd also like to see someone compete with a decent and open text-to-speech solution that gets wide adoption... And the idea of flagging fake reviews doesn't sound too bad (I haven't tried it.) I mean people are complaining about SEO making google unusable and fake news only ever getting more. I can see some benefit there - if done right.
But we definitely don't need a Clippy 2.0 or another smart assistant. And I don't think everything has to be embedded in a browser and make it yet more complicated and bigger, or implemented in the operating system. An add-on will probably do.
(Edit: And I sometimes don't understand Mozilla. Why not focus on their core product and make that exceptionally great? If they're already struggling... What's with all these side-projects and dabbling in AI anyways?)
