I'm not scared of AI advertising because it will be impossible to sell. There are 3 issues:

1. No marketing agency would ever have the balls to say "we've checked our database and there is no one who would click on your ad."
2. Any marketing department that gets told their ad has a near 100% click through rate would demand to be shown to more people because "obviously there's a massive audience for our product."
3. There would be situations where the AI could not find an ad that the person would click on and the AI would shit itself because it would be prompted to "always show an ad"

We already could have the option to only relevant ads but no ad company would because it's being paid to shove ads in front of eyeballs.
