josu··on El Salvador abandons Bitcoin as legal tender
They didn't, the IMF just offers better terms than the free market. And they are still doing their Bitcoin thing, this was just a small concession they were willing to make.
josu··on El Salvador abandons Bitcoin as legal tender
Inflationary legal tender is a novel concept.
josu··on El Salvador abandons Bitcoin as legal tender
Here is the retained purchasing power of each of the coins since the law was passed in September 2021:

Legal tender 1: -15%

Legal tender 2: +115%

Guess which one has been deemed a "Failed experiment".

josu··on El Salvador abandons Bitcoin as legal tender
They literally removed the term "moneda de curso legal", which translates as "legal tender", from Article 5.

josu··on El Salvador abandons Bitcoin as legal tender
While it is true that adoption remained relatively low, the reason why they abandoned it is that the IMF made it a condition for the Salvadorian government to be able to receive a 1.4B loan.
josu··on GPT-5 is behind schedule
> captchas

I suspect that AIs are already more effective than humans at passing captchas.

josu··on GPT-5 is behind schedule
It has replaced ~50% of my Google searches.
josu··on How WhatsApp became an unstoppable global cultural force
The US was one of the few countries in the world where there were unlimited SMS plans. So by the time Whatsapp came around instant free messaging was already ubiquitous. This wasn't the case for most other regions, where Whatsapp actually brought free unlimited mobile messaging.
josu··on Bitcoin is over $100k
What about the gold? We use dollars to measure that too.
josu··on Bitcoin is over $100k
Let's revisit this in 10 years.
josu··on Bitcoin is over $100k
>Bitcoin's price is simply another symptom of this.

Bitcoin is not the symptom, Bitcoin is the answer. People are not longing Bitcoin, people are exiting the dollar, the euro, the yuan...

josu··on FBI Raids Home of Polymarket CEO Shayne Coplan
Polymarket is crypto adjacent, and the current administration has been going against the whole crypto ecosystem. I don't think it's just about predicting that Trump would win.

josu··on iOS 18.2 Lets EU Users Delete App Store, Safari, Messages, Camera and Photos
Yeah, and that's arguably the reason why there is no European Apple, or Facebook, or Google, or Microsoft...
josu··on Concerns Raised over Bitwarden Moving Further Away from Open-Source
What alternatives do you recommend?
josu··on 1 bug, $50k in bounties, a Zendesk backdoor
I have a similar conspiracy theory for DDG, the rapper. I used to go to DuckDuckGo by typing "ddg" in Google. Now, it's all mentions to DDG the rapper.

>but which are subtly geared to concentrate wealth at the top.

Wealth tends to concentrate. So any action that creates wealth will also increase wealth concentration (in most cases). So unless economists, or anyone for that matter, try to construct theories that compensate for that externality, then most wealth creative theories will also have the effect of wealth concentration.

>Economists core moral value is maximum efficiency, but I think overall efficiency is better at a happy medium rather than a maximum.

You are talking about pareto efficiency vs pure efficiency and economists are well aware of this tradeoff. Vilfredo Pareto was himself an economist. A situation is pareto efficient when you can't make anyone better without making anyone else worse (your "happy medium"). Your claim is that "economists" don't care about pareto efficiency and only care about efficiency, which is absurd, they even defined the term. A good economist will lay out both the benefits and problems of their theory, and will propose mitigating measures for any negative externalities that it may cause.

josu··on Learning to Reason with LLMs
Kind of?

>We're hoping to grow OpenAI into such an institution. As a non-profit, our aim is to build value for everyone rather than shareholders. Researchers will be strongly encouraged to publish their work, whether as papers, blog posts, or code, and our patents (if any) will be shared with the world. We'll freely collaborate with others across many institutions and expect to work with companies to research and deploy new technologies.

josu··on Airlines are running out of 4-digit flight numbers
>Why not use alphanumeric characters?

Someone hardcoded that field 50 years ago and it's impossible to change the type. It would be easier to just abandon planes altogether, and set up a parallel transportation system.

josu··on Ryanair Boeing 737 MAX plunges 2,000ft in 17 seconds
Related information: In the US (maybe everywhere?) air travel is safer than railroad travel.

The railroad experience is usually much better though, I agree (compared to economy class).

josu··on Sleep deprivation disrupts memory
It's cool to back it up with data, but any parent who has looked after a newborn knows this.
josu··on Extracting concepts from GPT-4
Totally off topic, but I love that the external visualisations are hosted on windows.net!

josu··on I got tired of hearing that YC fired Sam, so here's what actually happened
I don't think this investment is like the rest, there was a clear conflict of interest in the OpenAI investment given that the CEO of YC was also the founder and one of the directors (?) of OpeanAI. And not only Sam, Jessica Livingston is also one of the founders of OpenAI.

This is not a comment on whether PG should have been informed or not, I don't know how YC operates.

josu··on How to recover lost Python source code if it's still resident in a running inter (2017)
I love that the research and recovery probably took longer than just rewriting the code; and I'm sure that I would have tried that route too.
josu··on Mindfulness interventions for teens decrease mindfulness, study finds
>We have the data to show that mindfulness works

Do we? (From "Has the science of mindfulness lost its mind?" (2016))

"A recent comprehensive meta-analysis of randomised clinical trials showed that mindfulness interventions only led to moderate improvements in depression, anxiety and pain, and very small improvements in stress reduction and quality of life. There was no evidence that mindfulness had an effect on other variables, such as positive mood, attention, sleep or substance use. Further, when mindfulness was compared with other interventions, such as physical exercise or relaxation, it was not more effective."

josu··on Whistleblower Josh Dean of Boeing supplier Spirit AeroSystems has died
According to this article there are 30[1]. Another whistleblower allegedly committed suicide two months ago [2].

josu··on Tesla failing to deliver Semi-trucks on time to PepsiCo, Sysco, UPS, and Walmart
Kind off. You don't need to spend the tax money helping the environment, you just need to restitute whatever utility those affected by the negative externality have lost. For example, people may be willing to accept an increase in CO2 in exchange of a direct transfer of $100 per ton emitted.

Assuming that tax money is being used effectively (lol), the negative externality could completely disappear with the right tax level. You could even turn driving into a positive externality if the tax is high enough, while still polluting.

josu··on Tesla failing to deliver Semi-trucks on time to PepsiCo, Sysco, UPS, and Walmart
In most European countries gasoline is taxed at more than 100% (or 50% of the price), so it seems that at least for passenger cars, the externalities are mostly mitigated.
josu··on Biden signs TikTok bill into law, starting clock for ByteDance to divest
>The sale will be for $30-50B (CI 50%), it won't include important ByteDance IP that will have to be recreated by a US-based company, likely Snap or X.

Why replicate it? Can't ByteDance license the IP to the US company?

What about Hong Kong?
josu··on NASA tries to jog Voyager 1's memory from 15B miles away
I tried with a few LLMs, and they seem to agree (sometimes) around 10^15 lumens. A light wouldn't work, but it seems that a nuclear explosion close to Little Boy's would do it.

PS: The best way to get an answer on the internet is to provide a wrong answer.
