To repeat myself again, the crux of the problem is;
AI companies are stealing our hard-won lifelong research findings, which we were already sharing freely, without attribution/credit and building upon them without informed consent nor compensation.
The AI companies are robbing the mathematicians by not involving them in major decisions about solving the leading/promising research problems in their domain. They are the ones who have identified the problems, its importance, promising approaches of attack etc. which have all been freely shared and which the AI companies have used to build their models.
For example, in the Navier-Stokes case, OpenAI could have easily informed the mathematicians like so, "hey, your research approach looks promising, do you have any objections to us using your research in our models and throwing a lot of compute resources at it so that we can finally solve it?" Every mathematician would have jumped at the chance since that is what he was doing anyway but at a small scale and far slower pace.
Instead OpenAI went behind the mathematicians back while building upon his and others work without attribution/credit nor compensation. This is plagiarism, cheating and despicable behaviour and should not be tolerated by anybody.
