Pretty crazy and no doubt a lot of these patterns will find their way in more subtly. The total global ad revenue for online is massive at nearly 1T. Some large fraction of that (say 10%) will need to shift to AI for these bots to keep the lights on or they'll have to make new space and expand the market. Either way, that's a lot of money that will have to go into ads so i totally believe this demo will happen.

I don't see such a huge shift happening though. Ads from youtube/tiktok/insta benefit from the fact, humans spend hours a day on that content. Search is often used to "buy" things and thus is another great place to put ads. Will people go to chatbots to "buy" things? Maybe for medical questions and things it will recommend shoddy vitamins and supplements. Will that pay the bills? I dunno. It will certainly be regulated in places.
