Almost certainly. There is a vast corpus of text which references hands and what they are used for. Likewise there is a vast corpus of images which include hands. A sufficiently advanced statistical model can infer that any image with 6 fingers is a fabrication provided that it has learned how to classify fingers and has enough linguistic knowledge. Contrast this situation with a primarily image based model which will struggle to differentiate what situations detailed hands appear in compared with a patterned rug.

There is an interesting “takeoff” point where models are able to generate enough “interesting” data to train themselves. Asking chatGPT for ml training data on various tasks makes me think we are close to that inflection point.
