There's a ditch by my house that the city put in. I roughly knew what it was, a big pit where rain collects and soaks into the groundwater. But I wanted to know the name of it and no amount of Googling could get me to the right answer. My query was too vague. The day that ChatGPT launched, I described the what it was and it came back with, "that's called an infiltration basin." That's when I knew Google was in trouble.
