I mostly agree with your comment, but I think we can put aside fair use and enforceability of the license in following manner: 1. I think whether AI training is fair use is for the courts to decide. In some sense a licence such as this could land a good case to force the courts to do so, as it could prohibit any argument that the training was in accordance to license and as such would require the trainers to rely on fair use exclusively. 2. Enforceability is always a problem with copyleft licenses. You can't expect that putting a restrictive license will completely stop infrigenment, but you create legal peril for anyone who decides to do so.
