Dear Keith, I recommend this recent interview with Colin McLarty https://youtu.be/81sPQGIWEfM?feature=shared which covers much more than your question, but puts a lot of things into context. Colin uses the word 'betrayal' in a discussion of how Grothendieck viewed how Deligne proved the last Weil Conjecture at about 32:34 and after. Grothendieck was very unhappy with how the conjecture was proved without going via the Standard Conjectures (which he thought had been used, when he first heard in while in Buffalo that Deligne had done it, without knowing the details). I have listened to the whole interview, but can't point to a single place where you'll get a good answer, because it's a bit distributed. But I would definitely say listen to the whole thing, it's really good. All the best, -- Dr David Roberts http://ncatlab.org/nlab/show/David+Roberts Adjunct Associate Lecturer School of Computer and Mathematical Sciences University of Adelaide SA 5005 AUSTRALIA CRICOS Provider Number 00123M IMPORTANT: This message may contain confidential or legally privileged information.

From the Guardian article: "a sense of betrayal by his former colleagues." https://www.theguardian.com/science/article/2024/aug/31/alexander-grothendieck-huawei-ai-artificial-intelligence Is there any discussion within the French mathematical community of the validity of that charge? References, please. I know this brings up some issues. I think it would be worthwhile to discuss them.
