Twenty-six Fields Medalists sign a warning
Three days after the Navier-Stokes announcement, a declaration signed by 26 Fields Medalists warned that AI companies treating unsolved problems as benchmarks does detrimental damage to mathematics, because it produces answers without producing understanding.

What happened
The Fields Medal is the closest thing mathematics has to a Nobel, awarded to at most four people every four years. Twenty-six of them signing the same document is not a routine event.
Their objection is not that the proof is wrong. It is about what a problem is for. A Millennium Prize Problem is not a task to be cleared; it is a place where mathematics does not yet understand itself, and the value of solving one has always been the understanding generated on the way.
Terence Tao, who signed, made the second-order point: the effect on how researchers behave. If a rumour is enough to trigger ten thousand agents at your problem, you stop telling people what you are working on.
What it points at
This is the most interesting counterargument on this site, because it is not about danger at all. Nothing here is about extinction or cyberattacks. It is a profession saying that being handed answers costs it something it needs.
Hold it next to the phage paper and the tension is clear: the same machinery that may give us antibiotics that work is also dissolving the practice that taught us how to find them. Neither cancels the other.
It also suggests something the alarm-versus-hype frame misses entirely. The harm here is not an accident or a misuse. It is what happens when the technology works exactly as intended.
What we do not know
The text of the declaration and the list of signatories are not linked here yet. This entry rests on reporting about it.
Editor's notewhat we make of it, kept apart from what happened
For a room in Leuven this is the one to reach for when someone says the worry about AI is an American internet obsession. Twenty-six of the best mathematicians alive object on grounds that have nothing to do with x-risk, and they are worried about their own field losing something.
It is also the cleanest way to give the room permission to be ambivalent rather than for or against.
