First of all, this wasn't a replacement for search, no search was claimed to have taken place. The screenshot from the complainant shows this was not in a search context.
Secondly, llms are daydream machines, we don't expect them to produce "truth" or "information". So the nytimes comparison feels very wrong.
Thirdly, this story is about a man who typed a text string into the daydream machine. The machine continued appending tokens to the inputted text to make it look like a sentence. That's what happened. Nothing to do with truth seeking or "protecting" big tech
