I was interested in whether mathematicians considered these proofs important and interesting. So I went through the quotes and picked those that are about the problems specifically, not impact on the community or comms - lots of people very pissed about that (c.80% of comments). I would say that nearly every person that touched on the problems solved or the solutions was impressed. "Quasi-Riemann is a result that I thought was complete science fiction" "I am stunned." "These were almost all the major open problems in my field!" "It does feel like the end of an era where the ability to solve problems was a distinguishing feature of being a mathematician." "Today my chief feelings are disorientation and bewilderment." "This timeline is crazy. I feel conflicted." "I am both amazed at the results and the technological advances and scared at the fact that the pace is much higher than I can keep up with." "I got really impressed by the resolution of the free factor problem [...] since I had been wrong about the expected outcome" "I was at first slightly underwhelmed by what was in there, especially given the results in my own field of arithmetic geometry." "Many of the AI-generated proofs appear to introduce clever new ideas that will be fruitful once digested, while also building upon the existing contributions of countless human mathematicians past and present" "I was initially surprised when I saw the resolution to the free group factor problem." "Assuming that these proofs are correct, I must say that I am very impressed about these results" "I was amazed by the scale and breadth of the recent results coming out of OpenAI in their announcement." "I am struck by how recognisable the individual parts are. The wilder creativity lies in their counterintuitive composition. I would probably have given up on these combinations, or talked myself out of trying them." "The scope of last night’s announcement is truly breathtaking. Until very recently, I would not have imagined that the frontiers of mathematics could move so far in one day. Beyond the remarkable list of problems that appear to have been solved, I am deeply impressed by the diverse forms of reasoning sketched in the documents that accompany the announcement." "Scrolling through the list of claimed results, I alternated between shock and apathy repeatedly." "If I had to pick one personally, the equivalence of strong Ulam stability and amenability (along with Dixmier’s problem) has particularly touched me, as I have spent several years thinking about it seriously. The solution seems to combine Furstenberg’s boundary theory with quantum circuits from quantum computing, how wild is that?" "Not a single one of the major open problems I have publicly mentioned throughout my career (whether in a talk, a lecture, an article, or even a grant proposal) was left untouched by the announcement. Everything has been claimed to be proved." "The “Big OpenAI drop” is nothing short of historic, possibly the single most important day in the history of mathematics thus far. Many of the problems with now proposed solutions in the Oct. 6, 2026 drop would represent huge contributions to their respective fields: quasi-RH, the second part of Hilbert’s 16th, Hilbert’s 10th over Q, the Hodge Conjecture of CM abelian varieties, Goldfeld’s conjecture, fast integer multiplication… They are undeniably huge contributions." "I was not expecting the magnitude of some of these results. Most particularly, seeing a proof of no zeros of Dirichlet L-functions to the right of Res=7/8 (and a second, short, proof of no Siegel zeros) is absolutely shocking to me, but there are many other breathtaking advances." "I was stunned by the claimed solution to determining the dimension of self-similar measures on the line (Item 148 in the Review) and related problems." "When I saw the 7/8 bound for the zero-free region of the Riemann zeta function among the released problems, I was genuinely shocked. I had always thought there was a broad consensus among mathematicians that the Quasi-Riemann Hypothesis was completely out of reach with existing mathematics. Apparently, we were wrong." "I find many of the results to be beautiful, and I’d love to understand them more deeply." "I was so surprised that they announced the solution to the Falconer distance problem, local smoothing estimates for wave operators, and bounds for Kakeya maximal functions. These were central problems in harmonic analysis, and my friend has worked on one of these problems for 6 years"
