**Mathematics Has Changed: A New Era Has Arrived**
In a landmark moment for the mathematical community, OpenAI's release of over 700 research papers on October 6 marked a turning point in the history of mathematics. Guest author Frank Calegari argues that artificial intelligence has moved beyond being a curiosity or a distant promise and is now an undeniable force in mathematical research. Rather than mourning this shift, Calegari invites mathematicians to embrace what is happening and engage with it honestly and openly.
Calegari's central message is one of optimism rather than anxiety. He challenges the instinct to feel threatened by AI's growing capabilities in mathematics, suggesting that the community would benefit more from adapting and evolving alongside these tools than from resisting or ignoring them. The title itself sets the tone: mathematics has genuinely changed, and it is time for mathematicians to act accordingly.
The post serves as a call to action for the broader mathematical community to update its assumptions, practices, and conversations to reflect the new reality AI has created. Calegari encourages researchers to think carefully about what these developments mean for how mathematics is done, shared, and valued. His perspective is grounded not in fear of what is being lost, but in curiosity about what becomes possible next.
