Annoying was a thing of the past. Look at the evolution of ads and content placement. With social media advertising being pushed to trigger massive anxiety and societal schizophrenia on some topics, imagine what can be done with personalized AI (especially if the buyers are well funded politicians, or state-backed malicious actors vying for territory, real estate, or natural resources where you live - the highest margin opportunities).
At first, In retail you had billboards and shelf space. The lowest quality ingredients your product has (example syrup bottled with soda water), the higher your margin was, the more you could afford to buy out shelf space in retail chains and keep any higher quality competition out. Then you would use some extra profits to buy out national ads and you’d become a top holding for the biggest investors. That was the low-tech flywheel.
In the Search Engine world - the billboards weee the Margin-eating auction-based ads prices and the shelf space became SEO on increasingly diluted and dis-informative content to fill the shelf-space side. In Video advertising, rage-bait and conspiracy theories try to eat up the time available for top users.
AI advertising if done right can be useful, but the industry that asks for it intentionally asks for obtrusive and attention hogging, not for useful. The goal is always to push people to generate demand, not sit there when they need something. Thus the repetition, psychological experiments, emotional warfare (surfacing or creating perceived deficiencies, then selling the cure). Now if you understand that the parties funding AI expansion are not Procter and Gamble- level commercial entities but state and sovereign investors, you can forecast what the main use cases may be and how those will be approached. Especially if natural resources are becoming more profitable than consumer demand.
