@duke_of_germany welcome to our safe corner of the internet, @flytox!
We can only speak for ourselves, and we've never added AI to our browser because our users are happy with taking the decision to use or not use AI in their own terms, instead of having it forced down their throats because it "has" to be built-in. Some thought we were being too "old-school" by not jumping on this bandwagon, since everyone else was doing it, but honestly, we're just listening to our community, the way we've always done.
