May I repeat David's (and other's) point, and politely request a response: what is the thinking behind this being on-by-default?

If it were off-by-default you'd have an easy argument to fend off the majority of criticism. If Mozilla management and devs sincerely think this is the future of browsers, add it in in all the ways you think it might be useful, but have it all off and very easily addable (as David outlined).

If it is really useful to people, users will be clamouring for it, and you can go from there.

I can think of no way it could make sense to have it on-by-default, unless you count the fact that in that scenario lots of less technical people will then simply put up with it, and be added to the stats of "AI users" on Firefox.

Am I missing something? How does it being on-by-default serve anyone, and in what specific ways does it serve them?
