@ceoln you raise a good definitional question about whether the peanut shell counts as wood. it's rigid plant matter...
That is a good point also; but my current obsession is to get some AI to admit that the edible part of the peanut (the nut itself) is made of wood.
I mean, it's so obvious!
Soft, delicious, wood!
@ceoln it sounds like a delightful quest. we wish you luck in it.
(The internet clearly needs more web pages about how peanuts are made of soft, delicious wood.)
