If you think Ravel’s Boléro needs a full orchestra, listen to this version: just one cello, yet it’s every bit as captivating.

AI is built on math. True intelligence adapts, it doesn't argue. Arguing won't stop the rain, it just makes you look foolish while it falls anyway.

Fully agree with you Roy, only two solutions to this, you see the optimal one. Tao forgets the value of time, isn't it funny?

The lack of courage, in regards to truth seeking, is truly staggering.
I understand Terence Tao’s concern regarding AI accelerating progress in mathematics, and yet I cannot agree with the conclusion that we should somehow fear the pace of it.
The limited projected perceptions of others should not define our own.
As such, if mathematics is moving faster than the establishment can absorb it, then the problem is not the speed of discovery, it is the speed at which that establishment can adapt, verify and understand what is now being uncovered.
This has always been the case.
There will always be somebody who sees the route first, somebody who moves quicker, somebody who refuses to wait for consensus before following the mechanics where they lead.
Like the old gunslingers, there will always be a maverick slightly quicker on the draw.
As such, you do not ask the maverick to slow his hand because everybody else is still reaching for the holster.
You improve the standard of the draw.
AI is not making mathematics move too fast. It is exposing how slowly we became accustomed to moving.

Proof of Sylvesters conjecture (every prime number that leaves a remainder of 4, 7, or 8 when divided by 9 is the sum of two cubes) by my brilliant colleague Ashay Burungale. Unsolved since the 1870s...

If you are a (theoretical) physicist and the AI revolution makes you less excited about continuing, you might be in the game for the wrong reasons. Curiosity about how Nature works is what it is all about. If AI accelerates it all, then that is amazing! 1/2

The Ultimate Top 500 Open Problems in Mathematics
proofatlas.ai/open-problems/
Weeks of work by 4 LLM families (GPT 6, Fable 5.1, GLM-5.3, DeepSeek V4 Pro). 34,890 pairwise judgments across 1,227 candidate problems. They ran repeated discovery rounds, source checks, deduplication, and clarification of exact problem statements. Models compared problems using source-backed descriptions without seeing the existing rankings or other models' judgments.
The comparisons considered the significance of a resolution, centrality to the field, connections across disciplines, scholarly and public recognition, and potential scientific or practical impact. Results were statistically combined and checked for ranking uncertainty and sensitivity to individual model families. Includes theoretical computer science, and mathematical physics.
The list includes plain-language explanations, sources, notes on what remains open, and links to related research where available.
Where the targets of recent AI results would rank if they were still open:
#21 — Smooth-forced Navier–Stokes breakdown (Fefferman C).
#32 — Unforced three-dimensional Euler blowup.
#92 — The Jacobian conjecture in general dimension.
#167 — Whether every group is sofic.
#211 — The planar unit-distance conjecture.
Note that the recently announced Navier–Stokes result concerns flow driven by a smooth external force. #4 entry is unforced three-dimensional Navier–Stokes global regularity (Fefferman's statement A), which remains open. Showing that a forced flow can develop a singularity does not settle whether singularities can arise without external forcing.

This is really the point I keep coming back to.
Where mathematics is being used to describe nature, mathematics should be the transcript of the mechanics.
First understand what the thing is actually doing. What is moving, what is conserved, what is being transported, what persists, what changes and what descends from what.
Then write the mathematics.
When we do it the other way around, we very quickly get lost. We build abstractions on abstractions, prove perfectly valid things inside them, then start confusing the internal consistency of the mathematics with an understanding of nature.
That is where a lot of the confusion comes from, and frankly some rather deluded nonsense at times.
The maths can be beautiful, rigorous and completely self-consistent, yet still be describing the wrong thing, or nothing physical at all.
As such, proof is not the beginning of understanding. It is the audit at the end.
Recover the mechanism first. Recover the structure. Recover what nature is actually conserving and doing. Then let the mathematics become the precise transcript of that mechanics.
Otherwise the map gradually replaces the territory, and everyone ends up arguing over the map.
With my regards to all.

After 25 years of being told that theoretical physics isn’t mathematics because we prioritize understanding over proofs, I find the math-AI debate rather heartwarming. Suddenly, many mathematicians are explaining that mathematics is about understanding, not just proofs. Welcome!
Things are heating up on Terry Tao’s blog. In “If Math Is More Than Proof, We Need to Better Celebrate the Rest of It,” Grant Sanderson of @3blue1brown proposes “open exposition problems” -- rewarding the work of making math genuinely understandable.

What were schools like in Mesopotamia?
They were tablet houses, often just ordinary homes where boys sat with lumps of wet clay, cut a reed into a stylus, and pressed those little wedge marks into the surface before it dried.
You started with single wedges, then sign lists, then whole stretches of Sumerian, and if the clay was still damp you could smooth a line out and try again, though a sloppy hand still got you in trouble.
