When will it do this exactly? Will we be watching AI generated movies and listening to AI generated music that is altering our politics? I don't see the avenues you see for AI to lie to me, perhaps someone who uses social media, or reads news websites, or opens spam emails might find themselves vulnerable - but I think you can live a good life without ever exposing yourself to or caring about this kind of nonsense.
I should point out I don't use Amazon, nor would I use any retailers website to inform myself about available products when I need to buy something.
