Kinda crazy how Tylenol didn’t unleash its autism causing power for decades until the diagnostic criteria changed
US immigration enforcement over 3 decades: Clinton/Bush eras dominated by returns at the boarder Obama shifted to removals of people already here Trump reduced overall numbers Biden used Title 42 expulsions because Covid Total enforcement peaked in early 2000s at ~1.8M/year
RFK Jr in April: we are going to do a brand new study to find out what causes autism. Gold-standard science. Who knows what we might discover! … RFK Jr in September: turns out all my preconceived notions from 20 years ago are exactly correct!
Deleting X for a while. Not good for mental health. It was becoming a cesspool for a long time, I didn’t see it because I was (as everyone should) ignoring the algorithmic For You feed. But now the toxins are seeping into my carefully curated garden Please be good to each other
To be clear nobody is saying “you will always need massive scale to train great models”, but rather “there are massive returns to massive scale.” There will be distillation and efficiency improvements! But K2-Think couldn’t have happened without o1 coming first (through scaling)
Exactly correct. People are seeing what they want to see.

I’m worried I might be misconstrued here IT DOES NOT MATTER WHAT THE SHOOTER’S MOTIVATIONS WERE There are murderous crazies on all sides of the political compass. We non-crazies need to band together and say, clearly and forcefully, “we don’t want you in our coalition”

There is broad consensus affirming what parents already know — mandatory active school shooter drills are deeply traumatizing for children and have no evidence of decreasing fatalities. We should not use taxpayer dollars to mandate kids’ participation in ineffective strategies…
The thing is, it would be so easy: take the speech Trump actually just gave, and remove the word “Left”. It would be a solid, sweeping condemnation of political violence wherever it comes from, which is actually what the country needs right now.

Criminals, even the worst of them, are not mutants that we can torture without remorse. Yes, sometimes they need to be removed from society for the greater good, but every time we do this it is a great tragedy. Thank you Kelsey for your powerful ideas.

Trump has had 5 years to produce even a single credible bit of evidence that the 2020 election was “stolen”. He has the levers of power and can conduct any investigation he wants, yet fails to produce such evidence. This is, in itself, very strong evidence against his claims.
JD “I don’t give a shit” Vance says killing people he accuses of a crime is the “highest and best use of the military.” Did he ever read To Kill a Mockingbird? Did he ever wonder what might happen if the accused were immediately executed without trial or representation??…

Our pediatrician (not antivax) told us the only reason to do the first shot so early is so that the rest of the hep-b vaccine schedule lines up with the schedule of wellness checks. Uptake rates drop a lot if you make people come in for extra appointments.

People seem confused, thinking “due process” is some extra thing we do because we like someone. If they are a criminal, why coddle them by offering “due process”? No, it’s literally *how you know if someone is a criminal or not*. You need evidence! This is not hard!
The argument is literally, consistently, transparently, explicitly: “Those who vote with me are courageous heroes. Those who vote against me are not just wrong, but evil, and want to destroy you.”
