But relevant to the topic at hand, do any of those sources regularly make it onto the search engine results page? Is the quality of Forbes, Cnet, Reddit, Wikipedia and Quora clearly better than these AI generated responses in some way?
I know there are expert vetted information sources, but you generally have to pay for the quality and they do not get linked to from Bing and Google.
I don't know exactly what he was referencing but the easiest way to verify the authenticity of points on issues where there tend to be two sides saying mutually incompatible things is to look at the overlap of what they both say is true. That is going to usually be true. And all it takes to find that is to look at sources for both sides.
Expert vetting doesn't even touch the underlying problem, because the pursuit is not expertise, in and of itself, but objectivity. And that's something far scarcer than expertise, and increasingly fleeting in today's world. A Chinese expert is probably going to have a different perspective on e.g. the Uyghurs than an America expert on such, even if both are in no way trying to mislead but giving their most sincere analysis of the situation.
Even on topics that are not conventionally controversial, you'll find a similar issue. Ask two astrophysicists of different worldviews on dark matter, and you are going to get two very different answers that, in many ways, will be incompatible. Simply "believing" one over the other doesn't really make any sense, nor does randomly polling astrophysicists and taking that as the definitive truth.
This is a great summary of this issues with trying to even determine objective reality. I would say that the simple popular consensus approach is not even that great because there are plenty of things in the past that have had consensus that were later determined to be objectively false.
My point was even a step before this, that even getting the consensus facts correct is a major challenge when the internet is written by children, bored volunteers, mechanical Turk contributors from across the world, adversarial actors, and content producers churning clickbait. Having a professional journalist investigate a topic, then have a separate professional fact-check, and yet another professional edit all for a publication that is trying hard to maintain a reputation and will publish retractions if necessary is all miles better as a starting point for determining truth, but sadly that cultural activity is nearly dead.
