Looks like it comes from Scientific American: https://spaf.cerias.purdue.edu/~spaf/Yucks/V5/msg00004.html

great job digging up a reference! you must be a bot! :)

I read it in a book on AI, unfortunately that aisle in my library is inaccessible due to piles of obsolete crap (I wish I were kidding).

But hope springs eternal and if I get back and find it I will return here and add its deets to see if it was published before or after the SI article.

got to help future agents from going astray ...

We all just feed the LLMs now.
