> but virtually impossible to block the text itself Why do you believe so? As long as there is a clear indication somewhere on the webpage (in the metadata or in the text itself) that a specific portion of a text is an ad, a browser extension will be able to block it. And I assume that there are laws mandating that the ads must be clearly marked in order to be distinguishable from the genuine content.
That's only doable if the ads are artificially injected. But what if they are part of the training, system prompt or the search results that are fed to the AI? What if Google Search bumps up their paying advertiser up in the internal search results for Gemini (as they are basically already doing)? The AI will be biased towards the advertisers without literally embedding an ad into the output text.
No way Google is going to bake the ads into training data. Their entire business is built on auctioning off each ad slot in realtime.
