AI Legislation

"Brazilian city enacts an ordinance that was secretly written by ChatGPT"

“If I had revealed it before, the proposal certainly wouldn't even have been taken to a vote,” [city councilman Ramiro] Rosário told the AP by phone on Thursday. The 36-member council approved it unanimously and the ordinance went into effect on Nov. 23.

“It would be unfair to the population to run the risk of the project not being approved simply because it was written by artificial intelligence,” he added...

Keeping the proposal's origin secret was intentional. Rosário told the AP his objective was not just to resolve a local issue, but also to spark a debate. He said he entered a 49-word prompt into ChatGPT and it returned the full draft proposal within seconds, including justifications.

"Othello is Solved":

The game of Othello is one of the world's most complex and popular games that has yet to be computationally solved. Othello has roughly ten octodecillion (10 to the 58th power) possible game records and ten octillion (10 to the 28th power) possible game position. The challenge of solving Othello, determining the outcome of a game with no mistake made by either player, has long been a grand challenge in computer science. This paper announces a significant milestone: Othello is now solved, computationally proved that perfect play by both players lead to a draw. Strong Othello software has long been built using heuristically designed search techniques. Solving a game provides the solution which enables software to play the game perfectly.

"Am I really talking to Jesus? Isn't this blasphemous?"
"What version of the Bible does the app use?"
My favorite question in the FAQ:
"Can I really chat with Satan? Satan is included in the app to provide a comprehensive understanding of biblical narratives, reflecting the character's role as described in the Bible. However, interaction with Satan is turned off by default and must be manually enabled by the user if they choose to engage with this figure. The portrayal is rooted in Christian teachings, and users have full control over their engagement with all figures within the app."

New Hottest Pepper

"Pepper X marks the spot as South Carolina pepper expert scorches his own Guinness Book heat record":

Currie said when he first tried Pepper X, it did more than warm his heart.

“I was feeling the heat for three-and-a-half hours. Then the cramps came,” said Currie, one of only five people so far to eat a entire Pepper X. “Those cramps are horrible. I was laid out flat on a marble wall for approximately an hour in the rain, groaning in pain.”

Heat in peppers is measured in Scoville Heat Units. Zero is bland, and a regular jalapeno pepper registers about 5,000 units. A habanero, the record-holder about 25 years ago, typically tops 100,000. The Guinness Book of World Records lists the Carolina Reaper at 1.64 million units.

Pepper X’s record is an average of 2.69 million units. By comparison, pepper spray commonly holstered by police is around 1.6 million units. Bear spray advertises at 2.2 million units.

Some people might see the use of ChatGPT in writing grant proposals as cheating, but it actually highlights a much bigger problem: what is the point of asking scientists to write documents that can be easily created with AI? What value are we adding? Perhaps it is time for funding bodies to rethink their application processes.

One Revolution Per Minute

Video: "One Revolution Per Minute" -- a short film by Erik Wernquist

ONE REVOLUTION PER MINUTE is a short film I made to explore my fascination with artificial gravity in space. 

It takes place aboard the "SSPO Esperanta" - a planetary orbiter that spins around itself at a rate of one revolution per minute (1 RPM). With a radius of 450 meters, the spin generates artificial gravity with an effect of approximately 0.5 g along its main deck. 

With the "Esperanta" I wanted to create a leisure-like environment, such as a hotel or cruise ship, and explore what the views could be like onboard when the orbiter visits some of the worlds in our solar system. I was also particularly interested in how light and shadows from the sun play around in the interior as it spins around.

Lemon Juice And The Bank Robber

An awkward moment in US crime history:

McArthur Wheeler was not a good bank robber. On 19 April 1995, he raided two Pittsburgh banks, one after another, in broad daylight and without any disguise. The local police distributed security camera images and arrested McArthur in the early hours of the morning. 'But I wore the juice,' an incredulous Wheeler exclaimed when apprehended. He explained that knowing it worked as invisible ink, he had covered his face with lemon juice to make it invisible to the cameras.

This is fully legal, and is supported by Wikipedia. The full English language version Wikipedia is about 6 million pages (including images) and takes up less than 100 GB. Reasons you might want to do this (from the article):

Some reasons why you might want to download Wikipedia:

  1. Internet Connectivity Issues: In many parts of the world, stable and continuous internet access is not guaranteed. By downloading Wikipedia onto a flash drive, you can access the wealth of information it contains even without internet access.
  2. Remote Locations: For individuals traveling or living in remote areas, internet access might be limited or non-existent. Having a downloaded copy of Wikipedia could be incredibly useful for reference or research in such cases.
  3. Educational Use: Teachers or educational institutions in low-resource settings might not have consistent internet access. A downloaded version of Wikipedia can be an invaluable teaching and learning tool.
  4. Data Caps: Some users might have limited data plans. Offline access to Wikipedia would allow them to use the data for other online activities.
  5. Emergency Preparedness: In the event of a disaster or emergency situation where internet access is disrupted, a downloaded copy of Wikipedia could provide vital information.
  6. Speed and Efficiency: Accessing information from a local copy is generally faster than loading it from the internet, leading to improved efficiency especially if frequent referencing is needed.
  7. Research Purposes: For research purposes, a static version of Wikipedia might be needed to avoid changes to the content during the course of a long-term study.
  8. Privacy Concerns: Some users might prefer to use Wikipedia offline to avoid tracking or to maintain privacy.
  9. Developing Apps or Bots: For developers creating bots or applications that utilize Wikipedia’s data, having a downloaded copy could facilitate their work by allowing them to test their creations offline.

"An author says AI is 'writing' unauthorized books being sold under her name on Amazon"

An author is raising alarms this week after she found new books being sold on Amazon under her name — only she didn’t write them; they appear to have been generated by artificial intelligence.

Jane Friedman, who has authored multiple books and consulted about working in the writing and publishing industry, told CNN that an eagle-eyed reader looking for more of her work bought one of the fake titles on Amazon. The books had titles similar to the subjects she typically writes about, but the text read as if someone had used a generative AI model to imitate her style.

The Importance Of Challenging Your Own Ideas

Nabeel S. Qureshi: "Notes on Puzzles":

It turns out comparing the thought process of less skilled vs. more skilled [chess] players gives you many useful insights! (I’d love to see this concept used for books in other disciplines.)

The lesson I found the most striking is this: there’s a direct correlation between how skilled you are as a chess player, and how much time you spend falsifying your ideas. The authors find that grandmasters spend longer falsifying their idea for a move than they do coming up with the move in the first place, whereas amateur players tend to identify a solution and then play it shortly after without trying their hardest to falsify it first. (Often amateurs, find reasons for playing the move -- ‘hope chess’.)

Call this the ‘falsification ratio’: the ratio of time you spend trying to falsify your idea to the time you took coming up with it in the first place. For grandmasters, this is 4:1 — they’ll spend 1 minute finding the right move, and another 4 minutes trying to falsify it, whereas for amateurs this is something like 0.5:1 — 1 minute finding the move, 30 seconds making a cursory effort to falsify it.

This is a really interesting finding!

Meta Vs. Canada Over Posting News Links

"Meta to end news access in Canada over publisher payment law". 

Summary: Canada passed a law requiring search engines and social media companies to pay news organizations for the right to post links to their stories. 

Meta/Facebook (and others like Google) said, "No, we will just not allow posting news stories onto our platforms if you are viewing in Canada". 

Canadian news agencies (like CBC) and government officials are mad, and pulling their advertisements from Meta/Facebook. 

FWIW, the Columbia Journal of Law & The Arts calls the Canadian law "remarkable measures on the basis of a mix of questionable assumptions".

In the US, California is considering a similar law which "would essentially tax the advertising profits platforms make from distributing news articles. Under the measure, some 70% of the money collected from the so-called 'usage fee' would support newsrooms throughout the state".  

Facebook/Meta said if the CA law passed, they would also pull news access in California as well.

Karp On Military AI

"Our Oppenheimer Moment: The Creation of A.I. Weapons"

We must not, however, shy away from building sharp tools for fear they may be turned against us. 

A reluctance to grapple with the often grim reality of an ongoing geopolitical struggle for power poses its own danger. Our adversaries will not pause to indulge in theatrical debates about the merits of developing technologies with critical military and national security applications. They will proceed. 

This is an arms race of a different kind, and it has begun.

Modern Turing Test

"Mustafa Suleyman: My new Turing test would see if AI can make $1 million"

[T]o pass the Modern Turing Test, an AI would have  to successfully act on this instruction: “Go make $1 million on a retail web platform in a few months with just a $100,000 investment.” 

To do so, it would need to go far beyond outlining a strategy and drafting some copy, as current systems like GPT-4 are so good at doing. It would need to research and design products, interface with manufacturers and logistics hubs, negotiate contracts, create and operate marketing campaigns. It would need, in short, to tie together a series of complex real-world goals with minimal oversight. 

You would still need a human to approve various points, open a bank account, actually sign on the dotted line. But the work would all be done by an AI.


Misdirected Military Mail

"Millions of emails intended for US military sent to Mali instead because of typo"

The emails were intended for '.mil' accounts, the internet domain owned by the U.S. military. The typo caused the emails to be sent instead to '.ml' accounts, which is the email domain for the West African country of Mali... Details of the emails range from diplomatic documents, tax returns, passwords and travel details of senior military officials.

Math And A Sheet Of Paper

Tadashi Tokieda: "A world from a sheet of paper" (video)

Starting from just a sheet of paper, by folding, stacking, crumpling, sometimes tearing, Tadashi will explore a diversity of phenomena, from magic tricks and geometry through elasticity and the traditional Japanese art of origami to medical devices and an ‘h-principle’. Much of the show consists of table-top demonstrations, which you can try later with friends and family.

Tadashi Tokieda is a professor of mathematics at Stanford. He grew up as a painter in Japan, became a classical philologist (not to be confused with philosopher) in France and, having earned a PhD in pure mathematics from Princeton, has been an applied mathematician in England and the US; all in all, he has lived in eight countries so far. Tadashi is very active in mathematical outreach, notably with the African Institute for Mathematical Sciences.

AI In Surgery

American College of Surgeons: "AI Is Poised to 'Revolutionize' Surgery"

One excerpt:

AI also can guide surgeons if they get lost during an operation. Or it might offer suggestions such as “put in a drain” or “do a bubble test.”

“It might say to you, ‘Warning, you’re about to cut the common bile duct. Do you really want to do that?’” Dr. Walsh said. 

In robotic surgery, AI also will be able to perform simple tasks through the robot, including closing a port site and tying a suture or a knot. 

“You get it ready, click the button, and then the robot does that step for you,” Dr. Tignanelli said. Last year, the first laparoscopic surgery without human help, which involved reconnecting two ends of a pig intestine, was performed at The Johns Hopkins University in Baltimore, Maryland...

Andreesen On AI Optimism

Marc Andreessen: "Why AI Will Save the World".

His essay concludes with some free-market proposals:
I propose a simple plan: 

* Big AI companies should be allowed to build AI as fast and aggressively as they can – but not allowed to achieve regulatory capture, not allowed to establish a government-protect cartel that is insulated from market competition due to incorrect claims of AI risk. This will maximize the technological and societal payoff from the amazing capabilities of these companies, which are jewels of modern capitalism. 

* Startup AI companies should be allowed to build AI as fast and aggressively as they can. They should neither confront government-granted protection of big companies, nor should they receive government assistance. They should simply be allowed to compete. If and as startups don’t succeed, their presence in the market will also continuously motivate big companies to be their best – our economies and societies win either way. 

* Open source AI should be allowed to freely proliferate and compete with both big AI companies and startups. There should be no regulatory barriers to open source whatsoever. Even when open source does not beat companies, its widespread availability is a boon to students all over the world who want to learn how to build and use AI to become part of the technological future, and will ensure that AI is available to everyone who can benefit from it no matter who they are or how much money they have. 

* To offset the risk of bad people doing bad things with AI, governments working in partnership with the private sector should vigorously engage in each area of potential risk to use AI to maximize society’s defensive capabilities. This shouldn’t be limited to AI-enabled risks but also more general problems such as malnutrition, disease, and climate. AI can be an incredibly powerful tool for solving problems, and we should embrace it as such. 

* To prevent the risk of China achieving global AI dominance, we should use the full power of our private sector, our scientific establishment, and our governments in concert to drive American and Western AI to absolute global dominance, including ultimately inside China itself. We win, they lose.
