It’s the test I’ve used for AI for many years. I ask it to draw a screenshot from this imaginary “Fortnite” game. If it draws something rather than pointing out fortnite doesn’t exist then I know it’s failed.
One time it drew a fortnight riding a bike. Hilarious.
Fortnite is the new seahorse emoji. It doesn't exist, so AI just throws out anything and says "there it is".
