How in god's name—irrespective of how valid this is, and its very valid—is this even remotely germane to the issue of AI in mathematics? Rattling off incidents and making the case that there is discrimination and sexists in mathematics (yeah no shit), how is this related to the issue of AI that was raised in the letter? Are the complaints raised in that letter any less valid because the mathematicians who signed them make part of a community which has reproachable behaviour, both past and present? I really don't get it.
