ccppurcell··on Does Georgism work? Five years later
Here's a dumb question. If there was just one tax, the lvt, what would stop businesses sort of rediscovering income tax.

I mean putting a line on your pay slip called "lvt contribution" and then state the pre-lvtc salary in job descriptions and stuff like that.

Similarly with vat and related taxes. The incentive in both cases being to signal: here's what we would pay/charge if it weren't for the government. Which is presumably the current incentive to state before tax salary/cost (this assumption could well be totally wrong).

ccppurcell··on Enjoy Every Sandwich
Another way to interpret the advice is not to buy the airport sandwich.
ccppurcell··on Why I didn’t sign the Fields medallists’ letter
Crazy take. Whatever justification existed before exists now. Why is generation of proofs justified but not understanding? What's the point of a proof if no one understands?

And anyway a mathematician's lifetime salary is basically nothing. I think total worldwide mathematics budget is less than a tenth of a percent of GDP. Meanwhile, openai cumulative loss stands at tens of billions?

ccppurcell··on Flights cancelled at UK airports due to ATC issue
I'm going to guess that they have really good predictions, it's just that it doesn't benefit them at all to reveal those to customers.
ccppurcell··on On the Navier–Stokes Millennium Prize Problem
Reading between the lines here, and taking an admittedly very negative view of openai, but they train on user prompts. So if they hear a rumour that someone is about to make a big breakthrough, they have an incentive to scoop by running the model and hoping the solution is in the new training data. Also the statement from the mathematicians in question alleges that they tried to pressure him into academic malpractice. Just appalling timeline we're in, cheers.
ccppurcell··on An Alien Mind
I just read that book. Embarrassingly enough, given the context, I got chatgpt (or whatever) to recommend me a list of books based on ones I'd previously enjoyed and that came up. As a mathematician it really sang to me, given the current situation. Bearing the torch forward, I mean.
ccppurcell··on Discovery of a new OpenAI agent message board
Well they brought it upon themselves by making it about being tortured to death etc., instead of the much more reasonable economic and social risks.
ccppurcell··on LLMs and Self-Referentiality
Weird side swipe at Marx. Or not so weird I guess. Correct me if I'm wrong but I doubt Marx ever predicted that a workers' uprising would lead to classless utopia. It's clearly a necessary but not sufficient condition.
ccppurcell··on Brits would quite like their private messages to stay private
That just means it's not their top priority.
ccppurcell··on My favorite nonfiction books about cults, scams, and schemes
If you haven't read it already, Fads and Fallacies by Martin Gardner is a great book. A bit more focused on pseudoscience than on cults but Scientology comes up for instance.
ccppurcell··on Don't Paste the AI, please
I've been saying "ask chatgpt" when I don't think I have anything more useful to add.
ccppurcell··on Israel creates fake think tank in likely attempt to dupe AI chatbots
Do you believe that 30 to 40 Palestinians per night pose an immediate threat? Elsewhen in history, genocidal acts have been justified by claiming a non existent immediate threat (of disease, of economics, of fifth columnists, of terrorism).
ccppurcell··on Less Coffee, Better Sleep
Also high pollen count. I am much more sensitive to heat than my partner but she has allergies. We sort of alternate. Sleeping with AC all night has its own issues.
ccppurcell··on How the words we teach English language learners changed
Dinner originally had a meaning like "biggest meal of the day". That used to be midday, culturally shifted to the evening. In some places and some contexts the language followed but not in every case. In southern England dinner is typically in the evening but we still say "school dinners" for subsidised lunches and "dinner ladies" for the women who serve them.

Supper has always meant evening as far as I know but referring to the evening meal as supper became a marker first of the upper class and then of pretension. Hearing someone say supper is quite jarring for me.

ccppurcell··on Our position on open-weights models
He almost admits as much if you replace "America" with "Anthropic and openai" at certain places.
ccppurcell··on All major LLMs are lib-left. Even Grok, half the time
Reality has a left wing bias. That's a quote from something. Not sure I agree necessarily, but a plausible explanation.
ccppurcell··on Terrence Tao's ChatGPT Conversation about the Jacobian Conjecture Counterexample
Isn't it just what you studied in depth? I am not in this area but can understand what's going on "at a high level" here. But I studied no other science formally since the age of 15 (this is possible in the UK school system). So physics and biology just go over my head unless they are sufficiently mathematical.
ccppurcell··on Age verification is just a precursor to automated attribution of speech
I agree with your broader point but I'm always skeptical of the claim "we should teach xyz in schools!" Because, well, choose your least favourite subject at school. A language, history or geography, mathematics perhaps. How much do you remember? The reason you don't remember is because you weren't motivated to learn, since you didn't, at the time, think it worth learning. If you think kids are champing at the bit to learn systems thinking, or how to file taxes, or law or anything else really then you are unfortunately wrong.
ccppurcell··on Can you see three trees?
Tree cover is great but I wish cities would just consider shade a bit more. As the world heats up, it's insane that so many places humans need to be for extended amounts of time have enough shade for a handful of people at best and often nothing. I'm thinking long sidewalks, waiting areas, playgrounds.
ccppurcell··on GrapheneOS has been ported to Android 17
Which phone and is it android then? Maybe I'm out of the loop on Motorola. I just bought a pixel, thinking of trying graphene. I was a bit miffed about the lack of jack until my partner pointed out I hadn't used the one on my old phone for over a year. I'd like to in the future though.
ccppurcell··on Not everyone is using AI for everything
The job market being as it is, a lot of people simply don't have that luxury.
ccppurcell··on Pokémon Go Scans Trained the Navigation Tech for Military Drones
Everything you do online publicly is usable in principle. Might as well also be public good. And my understanding is that Pokémon go made use of the camera. The kind of data you add using street complete is like "does this crossing have a traffic light?"

ccppurcell··on Claude Fable 5
Hey man, fellow Brit here. The American view on certain aspects of British life is insane. I've lived in not one but two places that have been called Muslim no-go zones in American media. My main memory of living near the east London mosque is an elderly Muslim trying to offer my his seat on the bus (I was on crutches) while two drunk gammons looked on gormlessly.

On the other hand, it is quite alarming that I can no longer say I support all non violent protests against the genocide in Palestine because that would include the group Palestine Action. It's amazing that supporting them openly is essentially equivalent to supporting Al Qaeda.

ccppurcell··on Mathematicians issue warning as AI rapidly gains ground
Well exactly.

One way to make money is to create a great product that solves a problem people have and market it effectively. That's a sort of idealised situation, an aspiration, but it's what I would call socially valuable. Another way is to help people who are already rich move their money around so that they become richer, in return for a fraction of the increase in wealth. I personally have no problem with that, everybody has to make a living, but that is not socially valuable. It is debatable how socially valuable pure mathematics research is. But you take a fixed fee and all your best work is public domain.

ccppurcell··on Mathematicians issue warning as AI rapidly gains ground
I think you've slightly straw manned the lamentation there. Not that I agree with the lamentation, but using your talent to make the rich richer (which is what quants do, they are paid a fixed amount to provide a larger value up the chain), as opposed to advancing human knowledge, is the reason for the lament, not some sort of respectability issue.
ccppurcell··on My new obsession: A horse-racing board game of pure luck
It is a memory game yes! But still you can choose what to memorise.
ccppurcell··on My new obsession: A horse-racing board game of pure luck
I find pure luck games really boring. Why not just flip a coin and be done with it.

I also find pure skill games boring. I mean like running races. You might as well play "who's tallest?"

But I seem to be in a minority

ccppurcell··on I'm Tired of Talking to AI
Sometimes people will bring up the fact that Plato thought reading and writing were ruining real thought in response to things like this. Or "you won't walk around with a calculator in your pocket"

But there are two possibilities in cases like these. Either we will figure out how to leverage the newfangled thing to our advantage (like reading and writing) or we will figure out a way not to need it. How often do you really use the calculator on your phone to do arithmetic? Maybe it's just me but I almost never do. At least where I live, these days I can always split the bill by selecting my items on a screen (and frankly that happens pretty rarely). I know people who use LLMs for it!

AI is probably a bit of both. I think managers will one day realise that copy pasting screenshots isn't getting them far. Or if they don't, their managers will realise they're paying someone for nothing and fire them.

ccppurcell··on The sigmoids won't save you
Well it only works when there is no information at all apart from the past frequency.

It's the solution to the tank problem. You know that the enemy number their tanks as they're produced. You capture a tank and know its number, N. What's the best guess about how many tanks the enemy has produced so far? As a pure mathematical model with no other details, the best guess is 2N. Of course in reality you have some ideas about how long it takes to make a tank, how many resources the enemy has etc.

Analogously you have information about the way trends develop.
