"I don't think everyone except the extremely wealthy being on basic income is ideal or better than what we have now"

Seriously? One sixth of the U.S. population is food-insecure. You don't think that basic income would fix that?

js8··on AI Policy
Yeah. But, unlike China, the West doesn't seem to want to invest very much into real-world engineering. Except maybe military for forever wars, which is ethically way worse.

This is a side effect of capital accumulation. There's no one to buy the products (as low/middle class gets squeezed) so no reason to invest. Instead, oligarchs hold money in assets and compete over control, ultimately with violence.

I was about to say, it's not just IT industry, it's capitalism leading to this.
js8··on Why OOP Exists
Yes, you can express everything using lambda calculus. Kinda.. so why not use a thing that already exists? Why invent a new language (encapsulation) when previous (binding) suffices?
js8··on Why OOP Exists
That relates to another misunderstanding. These ideas like "everything is a function" or "everything is a category" are not there to help you understand complex system better.

They are supposed to help you build better foundations; the abstractions to better understand your complexity you need to build (or at least pick) yourself.

Good foundations then help you relate the abstractions. For example, the categoric dual of a product is a sum. We can apply it to relation (relational algebra), and we get that sum is data inheritance.

So that gives you understanding of how functions (foreign keys), product (relation) and sum (inheritance) fit together. This sometimes helps to build abstractions in a consistent way.

js8··on Why OOP Exists
Well, I just wrote a comment that could be considered an "OOP hate". I was debating whether to do it.

The point is not to be snug about it. Functional programming (and monads) are actually simpler. You just need to resist the urge to "make it more understandable".

Abstract math doesn't have good analogies to the real world. By trying to make an analogy with the concrete ("monads are mappable") you lose simplicity.

js8··on Why OOP Exists
Well, what I don't understand is the SW engineering propensity towards cargo culting and doing things the harder way than mathematicians do.

I see it with OOP, XML, design patterns, and other things, now with LLMs. (LLMs - you really want to build complex systems in badly specified natural language, compiled or interpreted with an inscrutable algorithm and possibly indeterministic?)

Is it the excitement from a new analogy? Or are engineers naturally empiricists, while the rationalism/empiricism distinction doesn't work in computer science?

I think we would be better off if we just learned functional programming and few abstract concepts (categories, monads). Simpler than OOP.

js8··on Debian polls its developers on AI: permit or ban?
What are your arguments for a ban? Why do you expect someone to listen if you didn't provide a justification?
js8··on Anthropic tells staff to work from home due to possible security team strike
But the soldiers didn't have the mobile phones then. This was possible by manipulation the information about reality those soldiers had.

For example, how Mallory can gain power over Alice and Bob who don't directly communicate.

First, Mallory tells Alice: "I am stronger than you. If you don't do what I say I'll kill you." So Alice decides to submit.

Then, Mallory takes Alice to Bob and says to him: "Together with Alice we are stronger than you, and kill you if you don't do what I want." So Bob submits.

This only works if Bob doesn't talk to Alice, otherwise they would together see the empty threat.

With more people, it becomes a bit trickier but hopefully you see how blocking communication helps to gain power over people. Often the blocking of communication is done through propaganda, e.g. Mallory might entice Alice and Bob to hate each other, so they wouldn't get together and figure he's the manipulator. Or Mallory might just kill someone randomly to motivate people not to talk to each other.

Anyway, this shows the importance of free speech (which is really a misnomer; it should be called a right to listen). If you can freely talk (and listen) to other people, you reduce your chances to being subjugated by someone.

(This is also why in a war, people are incentivized to dehumanize the other party and not to listen what they say, because together they could figure out that the real enemy are the war profiteers on both sides, colluding. And besides, killing is the most reliable way of silencing someone. That's why people should also universally reject killing - based on someone else's word - unless they are directly threatened themselves.)

js8··on Mathematics in the age of AI
Kinda pointless, because

a) I am already convinced that P=NP

b) You have to convince many other people as well (that you're a magic oracle), because for the effect to work, lot of people would have to work on the problem (or at least spend tokens)

Nevertheless, a plausible magic oracle (such as Lean-verified proof, even if non-constructive and incomprehensible for humans) would convince many to take a 2nd look.

"But seemingly models good at programming for example, would get worse at programming if you removed everything not-programming. Train a model solely on syntax, and it'll be worse than a general purpose LLM on syntax, in general at least."

That might be because emergence of capabilities to reason about programs requires abstractions (such as fuzzy and modal logic) that are rarely present in software sources. That doesn't mean the reasoning model itself has to be large; neither does it have to emerge from the ML training on large language corpus, we might construct it by different means.

js8··on If this is true, the hyperscalers are toast
I partly agree. Theory (of computation) shows it must be possible, however nobody has produced the small model (well, depends who you ask, what is small, article disputes that) and the database yet.

To go very small (thousands of rules) so that the reasoner can be understood by humans and proven sound - might be computationally quite difficult.

js8··on If this is true, the hyperscalers are toast
The cost you pay is in additional reasoning the SLMs have to do. As I write elsewhere, LLM "remembers" that "Socrates is mortal", or other commonly useful deduction. SLM might need to derive it first by reasoning from the DB, which slows it down. (Or worse, it might miss the correct reasoning because it's just too much side quests to follow.) But the advantage is flexibility.
js8··on If this is true, the hyperscalers are toast
I believe it is true, and likely there exists a class of even smaller models than what they call "small".

You can imagine a reasoning model as a huge set of rules that generate the next statement from previous statements (written in context). In that sense, a reasoning model can be compared to a logical theory - you have certain deduction rules which can generate new judgments.

Often, logical theories are structured that the rules are remade into axioms, and the deduction rule is only modus ponens (which corresponds to function application and is a building block of program execution).

In the case of an LLM, the set of rules (or axioms) they have in the theory is quite large, but most likely semantically unsound (with respect to their their own representation of truth) - that's why LLM's make mistakes.

It would be desirable to break the logical theory represented by LLM into a smaller set of axioms, which would:

a) remove rules easily deductible from the smaller core of axioms (for example, LLM doesn't need to remember "Socrates is mortal", as it can derive it from "Socrates is a man" and "all men are mortal")

b) remove rules that have low value (facts that aren't used often or have weak validity) which cause ruleset to become unsound

I suspect that's what SLM distillation is doing, to some extent.

The question is, how far this process can go? I personally believe there is a useful logic for commonsense reasoning that has less than thousand rules (still several orders more than your typical mathematical logic, but orders less than SLMs). These axioms do not contain much facts about the world, but that could be added.

So I believe there is a sweet spot (deductive core, encyclopedic shell) which we have not yet found (it's a little bit more formal language than natural language) but is very efficient for general reasoning.

I know, the goal was to strongman the argument.
js8··on Mathematics in the age of AI
Oh it would change a lot. It would be an enormous psychological boost for everyone to find a practical algorithm.

In any case, I think it's better to read PP as somebody would find a practical, albeit incomprehensible, algorithm for solving NP complete problems.

Although I probably disagree with PP, because even a candidate algorithm that mysteriously works without proof would have practical value, so this case is not predicated on proving.

I think a better example of genuinely practical but rather uninteresting (YMMV) mathematical proofs are proofs of convergence of numerical methods, FEM for example. (I have been through it in school, it was a torture.)

js8··on Israel creates fake think tank in likely attempt to dupe AI chatbots
I should have noted, my comment is about facts. Opinion you can have, if you think it's beneficial for you not to trust (or trust) some nodes, do so!

The public social graph would be about who is a human, that can certify facts. Their opinion wouldn't really matter until you chose it to matter for you. Them being a human witness would only add credence to the accounts of the facts they witnessed, nothing more. You can still choose to disbelief the event if you have a good reason to (for example, even if you might believe a guy from Russia is a real person based on his social graph, if he certifies an event in Michigan, you might be skeptical of that account and decide to lower your own trust in that person). So there is a difference between the shared social graph - which is about a collective belief of who is a person, and your own trust, which you can modify as you wish. Unlike with Google and other big tech providers, there is not a singular "algorithm for trust" that can be manipulated.

You seem to be saying it will fail because people are tribal. I believe it will not fail, because the benefits of knowing the local social graph of each person will outweigh the tendency for opinion to split based on tribe. And the reason I think so is that trust evolved and exists in society; we do not only trust ourselves, and that's only possible if something like a social graph can work. The only issue is the scale, which can be solved by using a computer instead of computing it in our little heads.

Mass reporting means spending huge amount of reputation which doesn't really invalidate reputation of people who still certify that the person exists.

The problem with the current systems is that reputation buying is not transparent. In my system, it would be a public record, who endorsed who. So you could go back and track the fake reputation.

Also real people have some TTL with their accounts. Unlike links, "I am real person" is not nearly as fungible.

js8··on Israel creates fake think tank in likely attempt to dupe AI chatbots
Hm, that's an interesting point. But wasn't problem of that model that the social graph (links) were not really public, but rather hidden within a search engine such as Google? Maybe if they are public the problem would be mitigated.
js8··on Israel creates fake think tank in likely attempt to dupe AI chatbots
Maybe.. too many other interesting things to work on.
js8··on Israel creates fake think tank in likely attempt to dupe AI chatbots
I am not really sure how it could be faked. The fake assurance, in order to work, must be connected to you.

By default you could choose not to trust. If you don't trust random strangers it's OK. So I don't see how it would damage someone's reputation worse than today.

It would potentially only add trust. Arguably, today we have bots because we have no other option than to trust without justification. With the public social graph, the trust above the baseline would be justifiable.

js8··on Israel creates fake think tank in likely attempt to dupe AI chatbots
I don't think you understand what I mean by public social graph. What I mean is that anybody could publish or withdraw statements of two forms:

- "I, owner of account A, certify that owner of account B is human."

- "I, owner of account C, have a reason to trust/distrust the certification of account A about account B."

The collection of these statements would be the public social graph.

The social graph would then be used to establish provenance of facts, which are statements of the form:

- "I, owner of account B, certify account A being witness to event X."

Now whether to believe this or not depends on whether A certified B to be a human, and how much you transitively believe that statement.

So there is a kind of reversal - your statement about your uncle being human helps him to certify what you say, and vice versa.

js8··on Israel creates fake think tank in likely attempt to dupe AI chatbots
I don't understand why people who don't like fake news and manipulation won't embrace the social graph as a public good.

If enough people were willing to publicly certify that their fellow contacts are human, anybody could then assign trust to each social graph node based on the trust they have in the path to them. It would completely decentralize the algorithms and remove the fake accounts as less trustworthy.

I think people tried this with PGP but it never really caught on.

They are not saying what the cause of the "downplay" is. It might be as simple as when scientists speaks publicly and present a consensus, they will stay on the safe side and give conservative estimates.

js8··on Working with AI feels more like leadership than coding
Leadership is same as coding.

Leadership: Given task to produce something someone wants (B), get an expert (A->B) who knows how get it from something you have (A). If such expert doesn't exist, build a team of experts A->C and C->B, for a suitable intermediate product C.

Coding: Given task to calculate something user wants (B), find a function (A->B) that calculates it from user input (A). If that function doesn't exist, build it from functions A->C and C->B, for a suitable intermediate result C.

js8··on AI has access to a vastly larger working memory than the human brain
Why would you want something you don't comprehend? How can you be sure it empowers you?

I think perfect rationality doesn't exist, because it is rational to reject something that you don't understand. So rationality of a given physical system will always be bounded.

js8··on Understanding is the new bottleneck
I feel like if they were skills under a reasonable definition, you should be able to name an expert in these skills, and how do we know they are an expert.

But I think you can't. It seems to me, instead, one is better at googling/prompting the better they are in a particular domain, but it only applies in that domain. Like knowing a jargon is not a skill, knowing the domain is.

js8··on Understanding is the new bottleneck
Talking to an LLM is not a skill, just like using Google is not a skill.

Why? One, the companies like Google or Anthropic or OpenAI are working hard for it not to be a skill. That's the whole point. Second, these system are opaque, so there is no understanding to happen, only superstition, which might be wrong or change tomorrow.

js8··on Understanding is the new bottleneck
Actually, project managers could learn a lot from computer science. For example, on scheduling - kanban is the way to go (that's what OS is doing), scrum is BS. Or on planning - planning has a cost which decreases the total throughput.

There is also a variation of Amdahl's law - if you automate more things, the predictability of remaining work will decrease, because it will now take more time.

Also, formal languages still trump natural language. Despite LLMs; I think it's a stepping stone to something better but "vibe coding" will turn out to be unsustainable.
