We should assume that at least a portion of the ads spending currently being channeled towards search would be redirected towards AI, but even then I question if the ad market is large enough to fund all the tech and media companies that rely on it. The ever increasing question to generate more value for the shareholders is in large part being funded by consumerism, gambling, borderline, or outright scams, and I question how much more value can be extracted by that route. We've certainly already crossed a lot of people ethical barriers.
