Gemini seems to have a user interface that, for the way most people encounter Gemini, is more closely linked to search results. This leads me to suspect that Google's approach to training could be uniquely informed by both current and historic web crawling.
That's not what I said. What I said is that the claim "LLMs aren't intelligent because they stochastically produce characters" doesn't hold because humans do that too even if they're intelligent and authorative.
That doesn't really prove anything. I could create a Markov chain with a random seed that doesn't always answer the same question the same way, but that doesn't prove the human brain works like a Markov chain with a random seed.
One thing humans tend not to do is confabulate entirely to the degree that LLMs do. When humans do so, it's considered a mental illness. Simply saying the same thing in a different way is not the same as randomly randomly syntactically correct nonsense. Most humans will not, now and then, answer that 2 + 2 = 5, or that the sun rises in the southeast.
I'm not making any claim about how the human brain works. The only thing I'm saying is that humans also produce somewhat randomized output for the same question, which is pretty uncontroversial I think. That doesn't mean they're unintelligent. Same for LLMs.
