I'm kind of surprised that recaptchas are 'training AI' at google. I went through a phase of trying to use tor just for the principle of it. So I was hit with a lot of recaptchas. And I really couldn't see how they were testing AI directly. Usually, its the 'pick pictures of road signs' and 'pick pictures of cars' and so on. Almost all images seem to be taken from streetview cars, or possibly waymo cars. So, the human doing the recatcha has to parse an image to extract the implicit depth information to pick out cars etc. Whereas google know the exact location of the image so know where the roads are etc, and probably have lidar scan so they know the depth information etc too. Picking a road sign out of a picture is kinda hard for a 2D image. Picking it out from a 4D scene created from all the different sensors their cars have, on the other hand, is a piece of cake.
