I would like to talk a little bit about the experience of living in the Roman ghetto in Renaissance Europe for you guys. Just to give a sense of why the idea that Nazis learned from the US is so offensive. A thread of uncertain length.
To start, the Roman ghetto was deeply overcrowded swampland.

A couple years (!) in the making: we’re releasing a new corpus of embodied, collaborative problem solving dialogues. We paid 36 people to play Portal 2’s co-op mode and collected their speech + game recordings.

i am begging every skeptic to find some middle ground, any middle ground at all, between rejecting speculation as sci-fi and refusing to speculate even slightly about what happens next
A relatively small number of people in certain jobs say that ChatGPT and other LLMs have made them more productive at work. But in the overall economy, it does not look like net productivity is up.
Most of the supposed value is in sci-fi speculation. “Imagine a machine that cures cancer.”

I honestly don’t get the value of this company. They hoover up energy and water. Their product constantly gets things wrong and, in extreme cases, coaches people into suicide.
And it’s all built on what seems to be malicious and vast intellectual property theft.
What does OpenAI offer the world?

Mr. Beast is actually an real world case of a paperclip optimizer
I would normally write a small little skit where Mr Beast does one of his little bits, but I don't know what he does, so let's just assume he has a poor person trapped in a glass box and he's going to stream himself breaking their knees because they owe him $3500 on a $500 payday loan.

Trump has been able to make so much headway against the constitutional system because the institutions that are supposed to hold him in check have adopted the posture that it's savvy to let him have his way. Now millions of people are saying "Are you sure? An enormous number of us disagree."

Opposing genocide in Gaza requires no opinion whatsoever on the innate character of the state of Israel or Zionism itself. It is a specific group of war criminals pursuing a criminal policy of collective punishment, not the Pure Spiritual Expression of the Israeli Will.

Today I spoke with Greg Bovino, a top U.S. Border Patrol chief, as he led dozens of feds in military gear through downtown Chicago.
He said they were arresting folks based on “how they look.”
“How do they look compared to, say, you?” he said, referring to me.
