    I thank the mathematical community for raising the issue and fighting this "cognitive offloading". I stand firmly with the declaration and will continue to do so. More power to human ingenuity and the grounding struggle that all mathematicians are much too familiar with!

    Comment

    For the same knowledge state—or for two equivalent cases twin agents—we must assign identical plausibility values. Consensus feels safe because individual accountability becomes diluted. Let us advocate for the logic of consistent reasoning from incomplete information rather than ontological randomness. This preserves the useful idea—structural consistency under incomplete information—without elevating consensus into a quasi-political or normative force. Treating AI systems as epistemically “responsible agents” can obscure the fact that they are optimization systems with constraints, not deliberative entities with accountability structures.

    Comment

    I reject AI as none of its advantages outweigh the harm. The huge ecological impact it has as we are experiencing an unprecedented world wide climate crisis. The exploitation of poor worker needed to label the training data and the catastrophic impact on their mental health. The absence of respect of consent ingrained in its operation through mass stealing of data. The bias it cannot escape from being trained on our biased history. It is a machine that blur truth and reality, cosplaying as something reliable while being harder and harder to check. Meanwhile, nothing AI can offer I cannot do myself with a little bit of time and learning. Ask yourself "What is a little bit of time and learning against the cost AI has ?" and if time is such an issue, ask yourself "Why ?", because AI is not the solution to this issue. As presented in the Leiden Declaration, the Mathematical world is not immune to the impact of AI. Some of us are part of its developing process so there is a certain responsibility we have to have toward it. There would still be so much more to talk about but I will end with a very concrete simple last question: "How can we blame our students to cheat using AI when sometime their own professor use it to create their test ?"

    Comment

    As a math student looking to join research in the future, I hereby sign this declaration. I hope human mathematicians will be credited fairly and that math research do not become an antomated process running in the background of a privately owned ai facility.

    Comment

    The declaration represents a clear statement of principles that I hope almost all mathematicians can join in endorsing. Many mathematicians, myself among them, are optimistic about the role artificial intelligence will play in mathematics research. But optimism is no reason to ignore potential negative consequences of these developments. Most importantly, we mustn't lose sight of our fundamental goal, which is to enlarge and enrich human understanding of the mathematical universe.  Our community, over many hundreds of years of working together, has developed a rough consensus about what it is we are actually trying to do. We don't spend much time explicitly talking about these values; now is the time to do so.
