   Comment

   I am particularly concerned for early-stage career mathematicians (including myself) by the impact that this technology will have on their professional trajectories in the short and medium term. They will be hit the hardest by all this FOMO. Besides the excellent points raised by the declaration, I personally believe that Mathematics and mathematical ideas thrive in slowness, which is antipodal to this Silicon Valley delusion based on hysteric speed and production.

    Comment

    I strongly endorse the Leiden Declaration. As someone who straddles academia and industry, and as editor-in-chief of three peer-reviewed mathematics journals, I believe the timing of this declaration is critical. AI will increasingly shape how mathematics is discovered, communicated, verified, and valued. Its wide adoption must therefore be guided by principles that protect rigor, transparency, attribution, peer review, and the human culture of mathematics.

    Comment

    The game is changing faster than we can play. It is paramount that leaders and those with concerns in our field express considered stances about what is happening, with appropriate warnings and topical recommendations. That is what this declaration is.

    Comment

    I support this declaration. I have one small comment: the document notes that "Technologies which affect the way in which mathematics is practiced may disturb the current system of incentives." The current system of incentives seriously is flawed in many ways, and I don't think maintaining the status quo should be our goal. However, we should work to improve it, not let it be corrupted by outside forces, as has already been done for decades by university administrators, journal oligopolies, etc.
