Those who succeeded at SEO are the same who will (and arguably, are) succeeding at AEO/GEO/AIO or whatever we want to call it. And more over, AEO has been gamed with false pretence of authority by hijacking influence via 'prestigious' channels - demonstrated with false attribution, press releases, reddit astroturfing or numerous other vectors. These are arguably the same techniques of early SEO, moral or not, by showing up and acting up in places one assumes authority comes from.
