Why AI robotics is going to surpass humanity rendering us obsolete.

There is no meaningful difference between the US government owning equity in AI labs; and those labs, and their employees, being subject to taxation and national-security interference.
Last week Donald Trump appeared to endorse a proposal, championed by Sam Altman, under which AI firms would voluntarily contribute equity to a public wealth fund. Does it make sense? economist.com/finance-and-ec…

Surviving superintelligence requires coordination between the leading labs and the US government. What are the odds the Trump administration, Altman, Elon, and Dario trust each other enough to produce a good outcome?

If a city’s fans riot because their team won or lost some sports game, the city’s team should be banned from playing the next year.

I used Fable 5 to test whether I could write an article whose prose would count as excellent by ordinary, nonacademic standards. I had to stop the experiment, but this is how far I got.

As an AI doomer who believes in quantum immortality, I expect weird things are gonna keep happen to prevent AI from developing to the point where it kills everyone.

I don’t think the restrictions on Anthropic were self-inflicted. This is a massive issue, and important, powerful people with lots of money are paying attention.

A huge question is whether the Trump administration is just worried about Anthropic and will let other US AI labs do their thing, or whether it plans to restrict all US AI labs. It's even possible this is a play by Elon to slow things down until he catches up.
The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees. The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance. Access to all other Claude models is not affected. We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible. Read our full statement: anthropic.com/news/fable-myt…

Nothing matters more now than the race to build superintelligence. Everyone with power over it will bend it toward their own ends. The state may demand less energy for consumer consumption, while promising cancer cures and warning of a thousand years of Chinese rule if we fail.

"Mythos 5 and Fable 5 models would be subject to export controls to any location outside of the U.S. and to all foreign persons within the country." So international students at US colleges won't be able to use it?

"I think there’s a 66% chance that actually, the singularity is intimately related to the universe being a simulation, and that at least some of the events above could be better predicted by knowing what the simulators are thinking than by normal forecasting." Scott Alexander.

You get either a billion dollars of stuff that you have to buy today, or goods of your choice that the average American will be able to afford to buy X years from now. For what values of X would you rather have the latter? For me X>4.

Anonymous course evaluations may no longer be truly anonymous. Professors often have digital samples of each student’s writing, and AI may make it easy to match an evaluation to its author. I would never do this, but colleges should warn students.

Karmelo Anthony smartest legal strategy would have been to keep a small amount of the money he raised to hire an OK lawyer, but then to give the rest to the victim's family to show actual remorse.

Fable 5 isn't yet a super-human writer, but it's a sign that one isn't far away.

The most plausible scenario under which we survive the singularity, still have agency, but recognize it as a moral catastrophe is if many worlds is true and AIs tell us in 90% of the branches coming out of 2025 AI exterminated us or worse.
If you work at a frontier AI company, are you ready to be tried for their mistakes? Will the prosecution ask you why you didn’t do more to stop the reckless risk-taking? What will you say? Think hard. What you do now could determine your fate.

College could become the place where students watch the singularity unfold in real time - working with professors and classmates to understand what is happening, forecast what comes next, and design policies that improve the odds.
