AN Alexis Nicole Nelson On Gastropod

“A lot of people love sending me a screenshot of the AI overview at the top of a Google search. I'll be like, hey, that's an LLM, which are famously bad at a lot of things, but especially bad at the natural world, because it's filled with so much nuance and variation. Last year I had to respond to a video where someone asked ChatGPT what a plant in their backyard was. ChatGPT said it was wild carrot. It was poison hemlock.”

And I'll be like, hey, so that's an LLM, which are famously bad at a lot of things, but especially bad at the natural world. Because why? It's filled with so much nuance and so much variation, which LLMs are even worse at than the other things that they are bad at. Last year, I had to respond to a video where someone asked ChatGPT what a plant in their backyard was. ChatGPT said it was a wild carrot. It was poison health. Hemlock, don't pull a Socrates internet, please. It's not worth it.

Nicola Twilley

To be fair, although Socrates did die from drinking hemlock, it was actually his plan, not a chat-GBT mix-up. Back in his day in ancient Greece, folks generally took the time to learn what their local plants were. Today, Diana says one of the best ways to do that is using that old school technology…
