Yeah. Even just doing casual research you run into troublesome censorship of information issues with these LLMs. For example, I was interested in the whole process of production of pennicillin and I had a long discussion going over all the principles from scratch: how to find, isolate, assay, and force evolve the most productive strains of pennicillin looking at how things were done historically, how to grow in aerated flasks with continuous feed nutrient systems (with discussion about corn steep liquor being a traditionally ideal feedstock because it both feeds it, but also keeps it under stress so it ramps up production), carefully decontaminating all inputs and isolating the output through a drip system through an oil barrier, using amyl alchohol, and sufuric acid for extraction along with how to actually produce those, etc. Basically it was a very interesting and enlightening session. However, then I tried to more or less restart the conversation on another occaision to clarify some points and I started off with questions incorporating essentially a summary of the first session. The LLM basically refused to because I was asking so directly and it was worried that I was actually trying to set up an at-home penicillin production lab.
So, basically, while you can get information bit by bit from these things, a whole web of probably mostly liability-based safeguards get in your way. That is one of the real concerns (to add to hallucinations, etc.) with AIs taking over as the interface to human knowledge: they will censor it. Not necessarily for sinister reasons (though I have caught LLMs directly presenting corporate press releases to certain questions rather than generated answers, which I consider pretty sinister), but just for the same reason people who frequent certain heavily corporate forums have started to say "Yahtzee" and "unalived", etc. rather than the real terms even outside those forums. Basically, we have to worry about access to information becoming a compartmentalized, dumbed down, lowest common denominator situation.
