It's crazy to me that somewhere along the way we lost physical media as a reference point. Journals and YouTube can be good sources of information, but unless heavily confined to high quality information current AI is not able to judge citation quality to come up with good recommendations. The synthesis of real world medical experience is often collated in medical textbooks and yet AI doesn't cite them nearly as much as it should.

The vast majority of journal articles are not available freely to the public. A second problem is that the business of scientific journals has destroyed itself by massive proliferation of lower quality journals with misleading names, slapdash peer review, and the crisis of quiet retractions.

There are actually a lot of freely available medical articles on PubMed. Agree about the proliferation of lower quality journals and articles necessitating manual restrictions on citations.

The assumption appears to be that the linked videos are less informative than "netdoktor" but that point is left unproven.

How long will it be before somebody seeks to change AI answers by simply botting Youtube and/or Reddit?

Example: it is the official position of the Turkish government that the Armenian genocide [1] didn't happen.. It did. Yet for years they seemingly have spent resources to game Google rankings. Here's an article from 2015 [2]. I personally reported such government propaganda results in Google in 2024 and 2025.

Current LLMs really seem to come down to regurgitating Reddit, Wikipedia and, I guess for Germini, Youtube. How difficult would it be to create enough content to change an LLM's answers? I honestly don't know but I suspect for certain more niche topics this is going to be easier than people think.

And this is totally separate from the threat of the AI's owners deciding on what biases an AI should have. A notable example being Grok's sudden interest in promoting the myth of a "white genocide" in South AFrica [3].

Antivaxxer conspiracy theories have done well on Youtube (eg [4]). If Gemini weights heavily towards Youtube (as claimed) how do you defend against this sort of content resulting in bogus medical results and advice?

Conflict of interest.

I believe we need to do something. I see the big corporations slowly turn more and more of the world wide web into their private variant.

Geocities was so far ahead of its time.

Google AI (owned by Meta) favoring YouTube (also owned by Meta) should be unsurprising.

This is absolute nonsense. Neither Google AI or YouTube are owned by Meta. What gave you the idea that they were?
