My time was wasted by LLM-generated nonsense just yesterday. I wanted to know when whistling tea kettles similar to the classic design we know today first became popular. The first search result I got was a 3000-word essay all about the history of kettles, so I started reading. You'll know you've found the same one I did if at various points it claims that the kettle was invented "ca. 8000 BC", "4000 years ago", "around 3000 BC", "15,000 years ago", and "approximately 906-1127 AD".
There are various other inconsistencies and things that make no sense at all by human standards, but it's written in an authoritative tone, looks pretty nice, and was the first result on my searx instance, appearing in the results from several well-known search engines. It wasn't immediately obvious to me that it's all bullshit, and there's probably at least some truth mixed in there somewhere.
It's not exactly something to panic over I'd say, but it sure is annoying.
What's the difference? They both speak Swahili, right?
