Toru raises fundamental concerns with which I agree. It is amazing to see the progress in VLMs such as Astra, building on the work of generations of scientists. But Astra doesn't cite what it is building on (I have co-authored a couple of in-hand rotation papers which might have been used in the Astra pen-spinning demo). I fully acknowledge that VLMs make the result of previous research much more accessible to the general public, just like encyclopedias and Google Search did earlier, and that is a good thing. However, in the past, society had mechanisms like patent disclosures and paper citations as ways of doing credit assignment. Should we not accuse these AI models of plagiarism if they don't cite their sources? Somewhat relatedly, I note the open letter by 25 Fields Medalists in response to the Navier Stokes result complaining about the disruption caused to the mathematics research process. Some people interpreted it as turf protection, but the point was more subtle. If certain kinds of creative work stops because incentives are disrupted, it is like farmers eating their seed corn.
