I&#8217;m wondering how much of this has already happened.<\/p>\n<p>In math, Daniel Litt has <a href=\"https:\/\/x.com\/littmath\/status\/1945940469759815854\">noticed a bunch of recent LLM-generated worthless papers on the Hodge conjecture<\/a>.  As examples, he points to <a href=\"https:\/\/arxiv.org\/search\/math?searchtype=author&#038;query=Hajebi,+P\">these<\/a>, four papers posted during the past month.  Unfortunately the arXiv does not seem to now have an effective way to protect itself against these things getting posted, or to get them removed once identified (Daniel identified them publicly two weeks ago, no indication anything will be done about this).<\/li>\n<li>Also on the arXiv is an <a href=\"https:\/\/arxiv.org\/abs\/2507.20816\">article by George Lusztig<\/a> which goes over some history, with this summary<br \/>\n<blockquote><p>By publishing this document I aim to rectify the historical narrative for the benefit of the mathematical community and of the general public and to ensure that proper attribution and academic integrity is upheld by all.<br \/>\nI trust that all readers -including Kashiwara- will recognize these established facts:<\/p>\n<p>(a) The canonical basis was \ufb01rst de\ufb01ned in my work [L90] and Kashiwara\u2019s subsequent contribution built directly on this foundation.<br \/>\n(b) The crystal basis is not solely Kashiwara\u2019s discovery.<\/p>\n<p>And everyone who knows the history would suggest Kashiwara to publicly acknowledge (a) and (b), to correct all false and misleading information once and for all.<\/p><\/blockquote>\n<\/li>\n<li>Another one has been added to the list of Leinweber Institutes for Theoretical Physics, discussed <a href=\"https:\/\/www.math.columbia.edu\/~woit\/wordpress\/?p=14841\">here<\/a>.

I especially recommend the part around 52 minutes in, where Tong advertises a crucial hole in our understanding of the Standard Model: the non-perturbative formulation of the chiral gauge theory of the electroweak sector, in particular the lack of a viable lattice formulation.<\/li>\n<li>Last month there was the <a href=\"https:\/\/agenda.infn.it\/event\/44943\/overview\">Open Symposium on the European Strategy for Particle Physics<\/a> in Venice.

The FCC project has been the leading proposal, but the crucial question is whether such a thing is financially viable.<\/li>\n<\/ul>\n<p><strong>Update<\/strong>:  Daniel Litt has also written about this <a href=\"https:\/\/www.daniellitt.com\/blog\/2025\/7\/17\/arxiv-in-trouble#comments-687968ad6b88170c46a36064=\">on his blog<\/a>.
