I’m stumped. As usual, I’m supposed to persuade a robot that I am not a robot. Does the bottom-center square contain a bicycle?

I know what René Magritte would say.

@JamesGleick Yes, those things are starting to be easier for AI to solve than for human beings. Perhaps the next step is that you have to make a certain number of mistakes to prove your human.
@frankreiff I see what you did there 😆
