chongli··on Mathematics in the age of AI
Moreover, the disdain you have for low-value output in mathematics is not unique to you

I didn't say anything about low-value output. No one actually knows the value of any particular piece of mathematics within that deluge. Mathematicians don't have a magical ability to differentiate high-value mathematics from low-value merely by reading paper titles and abstracts.

The dirty secret in the mathematical world -- that has been going on for a long time already -- is that papers get attention based on the reputation of the authors, not on the rigour or validity of the proof. The big headline-grabbing papers are getting read by mathematicians because AI researchers have leveraged media exposure to bypass the reputation network, but media exposure doesn't scale.

When everyone is using LLMs to generate proofs, only reputable mathematicians will be able to get their work read. And herein lies the crux of the problem: an exponential takeoff in the volume of output from respected mathematicians will leave a critical shortage of readers.

it could end up being far easier to reasonably direct and evaluate the research direction and output of AI systems than human mathematicians

That's baseless speculation. All indications so far are that LLMs produce proofs far longer and far more complicated than humans are capable of, such that only machines can check the proofs for validity. Digesting them into a human-readable interpretation of the results is an open problem.

And that's an issue why?

The issue is SNR: signal to noise ratio. Generating exponentially more mathematics, particularly if the process is indiscriminate or optimized for something other than usefulness or mathematical relevance (such as optimizing for machine-provability), does not imply that we get exponentially more applications. We may end up halting the progress of applications altogether as the entire capacity of the world's mathematical apparatus is consumed by the interpretation and investigation of machine-generated proofs.

You can already visit arXiv and find vast numbers of not-yet-published mathematical papers. Most should never be published. None of this junk is benefitting humanity in the slightest.

We have thousands of years of precedent that suggests that breakthroughs in mathematics tend to accumulate into broader technology breakthroughs in other domains.

That's a misconception. Only a tiny percentage of mathematics has seen any applications whatsoever. There are vast libraries full of mathematics no one (in this discussion, anyway) has ever heard of that no one reads anymore and has never been applied to anything.

This idea of trying to "prove all the math" with AI makes as much sense to me as using chess engines to try to "solve chess."

No, they're saying that what is true in mathematics is contingent, not absolute. It all depends on which set of axioms use, what assumptions you make.

The area of a triangle doesn't have 1 unique formula, it has many, depending on the system you use. A triangle in plane geometry has a different area than a triangle in spherical geometry, and different again in hyperbolic geometry.

When you get to studying the geometry of manifolds, you realize the area of a triangle can be any damn thing you want, depending on how you construct the manifold you embed it in.

A proof by contradiction that p = np is of no use to anyone, given that it wouldn't help you find any polynomial time algorithms for np-hard problems.
chongli··on Apple announces changes for apps in the European Union
I’ve already given one reason why the switch is a bad idea. Another reason is that powerful third parties such as Meta and Google could force users to disable their own protections and give those apps full access to all data as a condition of installation.

Ultimately, an option becomes a requirement and then the protection for users is totally gone.

You can say that about a lot of things in life. Legalized gambling, for example. Tons of people ruin their lives with it and this creates big externalities for society. But we tolerate it so that everyone has the freedom to gamble.

Apple on the other hand offers a locked down product that many people want because they don’t trust themselves. I think a lot of people have short memories for all the hacking and spyware that plagued Windows users a couple decades ago. I think we also need to remember that Apple is not the government so people have alternatives to buying their devices.

Personally, I think people should have the right to buy a locked down device. It’s not on Apple to provide open competitors to their product. And why should developers have a right to develop for the platform? Heck, I wanted the iPhone back when it didn’t even have 3rd party apps at all.

I assume an expert mode (where you can sideload anything you want) is what you are asking for. To that I raise the standard objection: how do you protect grandma from having a criminal social-engineer her into enabling expert mode and then having her sideload malware onto her device?

So that means I can finally put my 3rd party context commands into the main menu instead of having to always show more to see the legacy one?

Sadly I’m in a locked down corporate environment, so I can’t edit the registry. IT even closed my ticket when I asked for them to make the edit on my behalf.

I don’t use Windows on any personal machines, so there’s no way for this to benefit me. I hope it helps others who are frustrated by this though!

Are they finally going to fix the issue of having introduced a second right click menu that forces me to click “show more options” literally every single time I want to do anything?

I’d love to have my own password manager that syncs between all my devices without relying on a third party server, but I don’t know of one. Do you?

A physical notebook is so easily lost I wouldn’t even consider it.

You don’t have to get paid to make contributions to math. There are still loads of hobbyists making contributions around the world. The guy that found the aperiodic monotile was a hobbyist who collaborated with a researcher. There was a significant proof in combinatorics (lower bound on superpermutations) contributed by an anonymous 4chan poster!

Hobbyist mathematics may long outlive a lot of research mathematics, and I think that’s okay. There’s nothing in the human spirit of inquiry that necessitates academia as an all-powerful institution. Heck, there have been a lot of problems with the institution in recent years, and those have everything to do with perverse incentives and nothing to do with AI.

I have 200+ different passwords stored in iCloud Keychain, each 20+ characters long. How am I supposed to remember all of those?

Do you use the same password on every site? How do you deal with data breaches?

chongli··on The continuing "Q collar" scandal
Right, that’s what they do in sci-fi books and movies. But then those collars magically never need batteries replaced, service, or replacement. They also don’t have any issues with false positive detonations.

If the collar can be deactivated to be removed for servicing/off duty/retirement/replacement/etc then it can be hacked and replaced with a placebo.

The other obvious weak point is that you can’t surveil the guards 24/7 to make sure they don’t swap the live explosives collar with a placebo collar.

There is no more inertia in the academic sector than in the software developer sector.

That is not true. In academia you have extremely niche research specializations and tenure as two major contributors to inertia. In general software development you have an enormous amount of career mobility.

Software developers learn new languages, new frameworks, new tools, new development methodologies all the time. A string theorist who decides to pivot away from string theory essentially has to start their career over from scratch. It’s not even close!

No, I’m using the right one [1]. You are the one using a bizarre definition for your own purposes.

I can see there is no further productive discussion to be had with you at all. I bid you good day.

Those are some strong claims. I’m deeply skeptical of all of them.

I believe Terry Tao when he says the bottleneck will no longer be the writing of proofs, it’ll be everything else: reading them, reviewing, publishing, and teaching from them. A bunch of proofs that nobody reads are of no use to anyone.

That’s still comprehensible. Incomprehensible chemistry instructions simply could not be followed by any human. They would be of no use to anyone.

If I told you "don't use spin locks, call futex instead", do you think have gained an understanding of the Linux scheduler?

Yes, because I already knew what schedulers are, what spinlocks are, and if I want to know what futex is I can go look it up. Comprehension is within my grasp.

Your original claim, which you’ve repeatedly distanced yourself from (by trying to use comprehensible examples) but won’t admit to, was about incomprehensible stuff. That is, text that no human could possibly understand, ever.

You’re repeatedly engaging in intellectual dishonesty rather than simply admit that “human comprehension probably will continue for the foreseeable future”, which is really not a controversial idea at all.

No, my point was only to refute the idea that people need to be egotistical or moronic (the only two options) to cling to an idea past its expiry date. People could also be “pot-committed” career-wise. Or they could have myriad other reasons (identity, sunk-cost fallacy, etc).

Nowhere did I suggest that “the reason for discrediting string theorists is that they have financial stakes in the idea.” Please try to be more charitable than that.

That's because his examples are obvious and not at all interesting, since we've already seen them.

His original claim amounts to creating an AI that takes its place above humans as some kind of electronic God, delivering edicts to humanity that we cannot comprehend, but which somehow have value to us. It's unskeptical, pseudo-religious nonsense.

If an AI can communicate its findings to us in a way that we can understand it, then its findings are by definition intelligible to humans. Your claim was about texts for which this is not possible.

Where is the value in an unintelligible gibberish proof?

We already have countless examples of such filling up the arXiv, written by hacks long before LLMs started writing proofs. No one cares about them. You might as well build a box blasting radio static into the void. You could save a lot of electricity that way.

One person need not completely understand something for it to have value; it's sufficient for there to exist a shared understanding.

an LLM might e.g. break some cryptographic algorithm in a way utterly unintelligible to humans, but the fact that it works would be sufficient on its own to make all of us choose to abandon that algorithm and choose different ones.

No, that is the entire point. If it is an algorithm which accomplishes something useful, then it is intelligible as such. That which is incomprehensible cannot be understood even in part, so it provides no value as a bit of knowledge (unless you're looking for a strong random number source, I suppose).

Again, do you believe that there are documents, of any value, that humans don't understand?

There is no value in an undeciphered document until understanding is achieved, just as a lode of gold ore in some asteroid orbiting a distant star has no value until we can fly there and extract it.

If an LLM can help us understanding something then it was not incomprehensible, by definition.
