That seems to be a big part of it, yes. I think in part it’s a reaction to perceived competition.
Frankly I've seen enough dangerous hallucinations from LLM search engines to immediately discard anything it says.
Versus finding the answer by clicking into the first few search results links and scanning text that might not have the answer.
They do it by going out and searching, not by storing a list of sources in their corpus.
Because when I ask chatgpt/perplexity things like "can I microwave a whole chicken" or "is Australia bigger than the moon" it will happily google for the answers and give me links to the sites it pulled from for me to verify for myself.
On the other hand, if you ask it to summarize the state-of-the art in quantum computing or something, it's much more likely to speak "off the top of its head", and even when it pulls in knowledge from web searches it'll rely much more on it's own "internal corpus" to put together an answer, which is definitely likely to contain hallucinations and obviously has no "source" aside from "it just knowing"(which it's discouraged from saying so it makes up sources if you ask for them).
If anything, I have the opposite problem. The sources are the best part. I have such a mountain of papers to read from my LLM deep searches that the challenge is in figuring out how to get through and organize all the information.
When it gives you a link, it literally takes you to the part of the page that it got its answer from. That's how we can quickly validate.
The reason why people don't use LLMs to "trivially save hours or days of work" is because LLMs don't do that. People would use a tool that works. This should be evidence that the tools provide no exceptional benefit, why do you think that is not true?
Curiously, literally nobody on earth uses this workflow.
People must be in complete denial to pretend that LLM (re)search engines can’t be used to trivially save hours or days of work. The accuracy isn’t perfect, but entirely sufficient for very many use cases, and will arguably continue to improve in the near future.
