Some of you folks worry me. I had a quick look at a couple of definitions of "understand":
to grasp the meaning of - Merriam-Webster
to become aware of the nature and significance of; know or comprehend - Wordnik
I assure you, chips having electricity run through them neither know "meaning" nor are they "aware" of anything, any more than a light bulb is aware that it's on or off. They cannot, and will never, understand humor any more than they can "care" about winning a chess game.
It's strange to me that some of you sorta do the opposite of what atheists do. If I say "the world sure looks intelligently designed", they respond "no, no, it just has the
appearance of design". If I say "it sure feels like I have free will", they say "no, no, it just
appears that way to you". But when you actually do see the mere appearance of consciousness, you're ready to jump in with both feet - "It's real!"
That's me on the table:
