Is there reason to believe this is a good discriminator of human vs AI? I didn't see any about page, or statistic, or anything like that, but maybe I'm just missing it?

Of course not. It is clearly a fun toy.

Congratulations! You have proven you are human by complaining about the test instead of solving it. Redirecting you now...
