the problem is ads. there will always be people who will try to promote their results, and it will somehow arrive to ChatGPT. there will be chatGPT SEO, people will try to promote their answers so that ChatGPT will chose these answers. Think of "what's the best pizza in NY" - SEO would pollute the web with hundreds of different articles which places Pizza Foo as #1, and those articles probably be scanned by OpenGPT. The good part here is that you might be able to optimize your query like "what's the best pizza in NY, based on /r/pizza subreddit? exclude bots (based on their karma reputation)"
