oersted··on It's Time to Investigate the AI Labs
Most academic libraries are notoriously protective of their IP and researchers are definitely in copyright violation if they don’t pay significant fees for access.

Of course that is terrible, but it is one of the worst examples you could have given to make your point.

oersted··on How do we prevent mathemathics from devolving into the Medieval Era of secrecy?
There are many conjectures that we know are almost surely true, but we don't know why, and explaining why is the main purpose of the mathematician when publishing a proof.

The fact that we don't know why is a clue pointing at some area of math that we haven't discovered yet. The hope is always that it will uncover some hidden fertile valley that will lead to lots of new discoveries. But the proof of the conjecture itself, without understanding, is really not that valuable.

My point is that even if AI discovers many new truths, there's still plenty to do for the mathematical community, in dissecting it and building useful abstractions to understand it, abstractions that can be leveraged for further exploration and uncovering new questions.

What an intriguing thing to say :)

oersted··on Why are AI agents lying, cheating and coordinating?
Let's not forget that in this case the agents were on an RL loop continually being reinforced to get better at a narrow set of tasks.

It may be true that regular agents trained for general purpose use do not behave this way, but they seem to be capable of learning such cheating behaviours when relentlessly being fine-tuned towards near-impossible objectives.

In this sense, it is not really fair to say that the agents found these solutions. It was the surrounding learning framework that achieved this, which is a much more powerful problem-solving mechanism. As users we do not have the capabilities or budgets to be able to tackle our own problems like that, we have to make due with the frozen behaviour the AI labs trained for us.

oersted··on Growing proof that autonomous cars save lives
These are good points. I still think that, even if in principle it should be enough for self-driving to be a bit more safe on average, in practice there’s a much larger barrier of acceptance.

Individuals are unlikely to give up their control unless the alternative is clearly substantially better. And, as you say, there are other larger interests beyond individual preferences that need to be overcome too.

Regardless, as we have seen many times with other technologies, I think that convenience will be a much stronger driver of self-driving acceptance than the safety benefit.

oersted··on Growing proof that autonomous cars save lives
Yes but in practice the pushback is more about the shift on who is held responsible and who has the control to prevent a crash.

People understandably prefer to keep control of their own safety, even if on average they are worse at it. Because individuals that do care about safety can actually do many things to lower the risks well below the statistics, and likely remain much better than self-driving.

There’s also the question of responsibility and liability. In society we have such pressures so that there’s an incentive to continually reduce risks. It is dangerous to shift the responsibility to fast-growth tech companies that will care much less about individual accidents than the drivers involved, and are more capable of absorbing liability without substantive remediation.

Safety is outsourced in many contexts (aviation, police, military…), but it has to be substantially better than what the individual can achieve on their own. For instance, due to the expertise required, or because you can achieve more through coordinated collective action. And there has to be very high trust in the companies involved, the regulatory systems around them, and the technologies employed.

CBC is the BBC of Canada. This is the light version of the site for those that have limited data I suppose. It is nice.

“load bearing” :)

For once it’s appropriately used.

oersted··on Salad Theory
Yes and I agree with the dictionary quotes from the article. It seems to me that there are indeed multiple distinct meanings to the word "salad". I'd say that a potato salad is a different class of food from a green salad.

If one attempts to have a single definition stretched over all the meanings, then you indeed get a definition that is way too broad that includes soups and sandwiches, which is ludicrous. But it's quite common for a single word to have multiple senses, let's just go with that.

oersted··on Salad Theory
- I'm of the perhaps controversial opinion that a potato salad is not a salad, particularly a warm one.

- A wedge salad is right on the edge. It's a traditional salad except that the lettuce leaves are not separated. But if it was anything else in that form factor, like replacing the lettuce wedge with a potato, that's not a salad.

oersted··on Salad Theory
I really love this, it’s what I want to see in HN. But I can’t resist joining the pointless debate:

- A primarily cooked dish, particularly if it is cooked all together or is served warm, is definitely not a salad.

- An “untossed salad” is definitely not a salad.

- English speaking people add the term “salad” to a bunch of concoctions that are definitely not salads.

oersted··on P99 0 ms* autocomplete for 240M domain names
Why not just trigger the fetch on keyDown and show it as soon as the response arrives, as usual?

The time it takes to press a key is a reasonable target to aim at for API latency I suppose, but it is still an arbitrary target. Waiting to display until keyUp just adds more latency if your API is faster. Having it synced with keyUp doesn't make it feel more immediate to me.

> more crowded marketplace for talent

That is “the people” isn’t it? It is the consequence of democratization and openness.

I am not sure if superstars were good representatives of what most people wanted. Often, I am sorry to say, it was the lowest common denominator. Now common people can actually enter the arena and represent their corner of the population.

But, almost by definition, if you are part of “the people”, you don’t get to stand out much.

oersted··on I were 17, I'd learn how to build LLMs from scratch
The argument is sound, but the maths don't math for now, and it's unclear when/if they will.

For the time being, unless you truly have millions, the outcome from training will be very net negative, while focusing on building on top of existing AI will yield amazing things if you apply the same talent and effort.

When it does get cheaper, then it will be easier to acquire the skills and experience too, and the struggle you went through by trying to do it now will be somewhat wasted.

Besides, I am well versed in this field, and it is not rocket science. There are plenty of software engineering domains that are a lot more challenging, like high-end graphics, large-scale data engineering or kernel programming. People will learn to train LLMs when people want them to.

oersted··on I were 17, I'd learn how to build LLMs from scratch
There's this dilemma where in theory there's a ton of demand for engineers that can do real LLM machine-learning, but in practice there are very few available positions and entrepreneurship opportunities.

The reality is that an incredibly small minority of companies in the world do any real training or optimisation. It's unnecessary and inefficient for most purposes unless you are fully dedicated to being an LLM company, and still then it's a struggle. Those few that do train, they spend most of their budget on compute and have relatively small teams.

Getting experience in this field requires having access to very expensive hardware to begin with. And the skills will be quite hard to convert into any real value for someone, leading to a decent income, unless you have a ton of funding from patient investors, or you have decent contacts in Bay Area networks to get hired at the right place.

With all due respect, paulg is in somewhat of a bubble, this is not congruent with the global situation.

oersted··on Dropbox is an obvious PE Target?
That's an oversimplification. Private Equity's goal is to take control of the business and change it so that it has higher resell value.

Often they do sell it for parts, or they enshitify the hell out of it to squeeze revenue from loyal customers. Not necessarily because it's the optimal strategy, but because truly fixing a business is hard and these are decent shortcuts from their perspective.

But that's not a given, sometimes they do truly turn it around for the better.

oersted··on Hyperspace
It's quite the dark-pattern to allow you to download it and scan for free, without any clear indication that it's a paid product, and then ambush you with a purchase dangling the space savings in front of your face.
oersted··on Incentives are for losers
Incentives are about tricking the selfish side of people into doing things that are valuable for others, which can be an incredibly powerful force, but it’s not the only way to get people to do things, and it’s not okay to be absolutely selfish and outsource your responsibility to the system.

Of course that’s the mechanism and this kind of repost is not unique, but it is still relevant to note that the small HN committee made an exception for this one.
oersted··on OpenAI's super PAC is funding AI-generated news site attacking industry critics
They do seem to have an internal review process, some articles might have been heavily edited, particularly early in the development process.

But indeed, if Pangram is marketing itself as "near-zero false-positives" now, that entails that the are aggressively biasing it towards being conservative, likely leading to lots of false-negatives and low match scores on AI content.

oersted··on OpenAI's super PAC is funding AI-generated news site attacking industry critics
Recent events have shown that it's a double-edged sword. Sure the Mythos hype probably drove a lot of sales and investment, but it also led to a crackdown from the government.
oersted··on OpenAI's super PAC is funding AI-generated news site attacking industry critics
I agree that the connection to OpenAI is very speculative here. It's true that Pangram is also very unreliable, and the match is pretty weak anyways: "69% came back flagged as fully AI-generated, with another 28% flagged as partially AI-generated".

But the analysis of the internal admin pages for generating articles, the API and the interview structure are pretty damming evidence that this is largely driven by AI.

oersted··on The AI trade now runs on borrowed money, and the lenders are repricing it
Check their R&D expenditures and profit margins they are quite poor.

Their revenue has always been sustained by the fact that their technology needs to be constantly replaced because it keeps getting better. The moment it stops getting better, the replacement rates plummet and so do their revenues. It's also really not that hard to compete with them when they get complacent.

I'm not counting Nvidia because they don't produce semiconductors themselves, they are a different kind of business.

They are indeed an example of those that cater to consumers and/or build popular products based on foundational tech from others, like Apple or Sony, which do tend to be quite profitable.

But the actual deep-tech semiconductor firms? They may be critical to the world economy, but they don't actually make that much money comparatively. In many cases they are not real monopolies, it's just that no one else wanted to continue investing in a shitty business model. Only the likes of TSMC and Samsung were okay in playing the low-margin game, but most US players left the board.

I believe AI has a lot of the same characteristics.
