I gave a prompt to an AI image creator and the result was mind blowing. I asked AI to create a bicycle whose body should be shaped like the Epsilon symbol like backwards 3. And this is what I got. https://prnt.sc/7xC0yIkGV_K4
No gears or brake, so presumably for track racing, but with that very wide front profile it wouldn't be very aero.
If AI's grasp on physics is such that it considers that chain arrangement to be efficient, or the distribution of spokes stable, then civilisation is safe for a while yet.
