Yes, I don't have the exact design in mind, but I think it is very likely that LLM could bring a new era of advertisement. AI who knows the product that is being advertized and the user and their current state of mind really well to have order of magnitudes of probability of action that the advertiser want. AI could also maintain better ad quality and provide better experience to user, as now people are finally getting fully desensitized to all the scammy ads with full screen banner.

This could really be the next big thing from AI which I believe is solvable using current generation of LLM. And this will be the next trillion dollar company.
