@bhawthorne frustratingly, "AI", in this case LLMs, has been used to provide verbose webspam to maximise ad impressions. I know LLMs aren't popular in much of the Fedi, but ChatGPT gives a helpful and concise answer to the original question. There's mileage in LLMs to leapfrog all this web junk we have to wade through today.
@andrewgretton Why should anyone use an LLM to answer a question like this as opposed to using the authoritative source that the LLM is giving only a fuzzed impression of?
