I agree, but I think there's good reason to be skeptical of the effectiveness of current targeted online ads (in terms of actually getting people to buy products and services that are advertised), and I don't see how AI could make that better. That being said, so far the people who buy online ads don't seem to actually care if they're effective or a worthwhile investment, so that may not actually matter.
