Chinese scientists have developed,
The best shortest-path algorithm in 41 years!
A team from Tsinghua University has broken Dijkstra's "sorting barrier" - the first improvement since 1984.
Just use for a world-map 🤯

Unfortunate update as of today:
More calls from friends. The total wealth that has left California is now $1T.
We had $2T of billionaire wealth just a few weeks ago. Now, 50% of that wealth has left - taking their income tax revenue, sales tax revenue, real estate tax revenue and all their staffs (and their salaries and income taxes) with them.
In other words, by starting this ill conceived attempt at an asset tax, the California budget deficit will explode. And we still don’t know if the tax will even make the ballot.
California billionaires were reliable tax payers - 13.3% every year. They were the sheep you could shear forever. Now California will lose this revenue source FOREVER.
Unless this ballot initiative is pulled, we will not stop the billionaire exodus. With no rich people left in California, the middle class will have to foot the bill.
🚨 Michio Kaku Breaks Silence on NASA’s 3I/ATLAS Controversy
Famed physicist Dr. Michio Kaku has publicly criticized NASA for keeping the latest images of 3I/ATLAS hidden from the public — saying, “This isn’t something that needs to be classified.” 👀
Kaku discussed the object’s strange physical and chemical behavior, revealing that new data show 3I/ATLAS has lost its tail after passing close to the Sun — something almost no natural comet does. ☄️
The discovery has sparked intense speculation:
Could this object be artificial? 🤔
Dr. Kaku pointed out its estimated age of 7 billion years and unusually high nickel content, suggesting it might be made of materials far older — and tougher — than our solar system itself.
He also criticized NASA for delaying Mars Reconnaissance Orbiter images from October 2, warning that “unnecessary secrecy only fuels conspiracy theories.”
While Kaku admitted an extraterrestrial origin remains highly unlikely, he noted that even Harvard’s Dr. Avi Loeb, known for his propulsion theory, hasn’t ruled it out completely. 🛸
Whatever 3I/ATLAS truly is — natural or not — it’s rewriting what we thought we knew about interstellar visitors. 🌌

The reason (good) investors are more optimistic is that, for them, the outcomes are weighted. If you're just measuring percent correct, you win by predicting startups will fail. But if the outcomes are weighted, you look for big wins even at the risk of many small misses.
Credit where credit is due
I’ve been very impressed by Daniel Lurie and the turn around in SF
Things are materially better now compared to two years ago
Feeling down about the world and about myself.
Normal human things. I'm sure soon it'll be better. If you're down too, sending you love.
I'm hiding from the world for a bit, enjoying the Boston fall months, long runs along the Charles river.
I think humans are beautiful and fascinating and for the most part awesome.
The internet seems to want to tell you otherwise. I disagree, but I don't have the right words for it.
I'll probably do a long solo episode on Dostoevsky (especially Brothers Karamazov) at some point to help me articulate this better.
I love you all.
Ok this tweet about upcoming changes to ChatGPT blew up on the erotica point much more than I thought it was going to! It was meant to be just one example of us allowing more user freedom for adults. Here is an effort to better communicate it:
As we have said earlier, we are making a decision to prioritize safety over privacy and freedom for teenagers. And we are not loosening any policies related to mental health. This is a new and powerful technology, and we believe minors need significant protection.
We also care very much about the principle of treating adult users like adults. As AI becomes more important in people's lives, allowing a lot of freedom for people to use AI in the ways that they want is an important part of our mission.
It doesn't apply across the board of course: for example, we will still not allow things that cause harm to others, and we will treat users who are having mental health crises very different from users who are not. Without being paternalistic we will attempt to help users achieve their long-term goals.
But we are not the elected moral police of the world. In the same way that society differentiates other appropriate boundaries (R-rated movies, for example) we want to do a similar thing here.
