AI is a powerful technology working in an unhealthy advertising ecosystem. It is unlikely to have a significant impact on digital advertising because of three factors related to the imperfections of the current ecosystem. The first is that targeting isn’t working all that well anyway. And as third-party cookies are deprecated and the present effect of Apple’s privacy policies combine, the data that feeds AI will not be a great training set. Secondly, bad actors in the ecosystem are faster than good actors and will use AI to improve their fraud. Finally, economic expectations are such that if AI has any impact, it will be used to replace human thought workers and not improve the process of advertising.
