Don't make me tap the sign

Large language models are slot machines that pay out in confidence, not information

If the information is bad (it often is) no one cares

But if the confidence was bad no one would use it 🤔

Luckily for the compulsive use companies want to promote, it's always confident

you don’t understand bro, if we didn’t lie, no one would buy our product 😩
Consider the implications if ChatGPT started saying "I don't know" to even 30% of queries
- a conservative estimate based on the paper's analysis of factual uncertainty in training data. Users accustomed to receiving confident answers to virtually any question would likely abandon such systems rapidly.

If we can just degrade the status of a targeted group a little bit more, I’m sure we can back away from the cliff edge of fascism

I'm kind of shocked that anyone is still proposing technocratic solutions to the "debate" over immigration. Even if this were a good idea (and it is not), Republican elites and media will never tell their base about it. You can't policy your way out of a propaganda problem!
But we could also go much further. One idea might be to tax immigrants themselves at higher rates and restrict federal benefits until immigrants have met some threshold of tax payments or achieved permanent residency.6 This is not a prospect that brings me joy. But I do think that these are necessary preconditions to warming the public to the idea that the economic math of immigration works out in our favor.

Jay Bhattacharya was nominated by Trump to spread lies to help the right’s political project.

Because that’s what Bhattacharya did for four years after 2020. Authoritarians and their lackeys need lies.

Truth is:
**Bhattacharya and RFK** politicized science, then and now.
Bhattacharya, MD, PhD
@NIHDirector_Jay At least two of the authors of this piece were in charge of the @CDCgov during the era when it embraced politicized school closures and covid vaccine mandates. For them to criticize Sec. @RobertKennedyJr for his
efforts to restore gold standard science to the CDC harms public health.

What could be more exciting than watching Euplotes scurry around under the microscope? How about adding some raptorial predation by supergiant cannibal cells?

Cells can form patterns within themselves just like embryos do. How? Connie Yan's new preprint shows how the anterior-posterior cytoskeleton pattern in Stentor is dictated by regionalized scaffolding proteins

An indigenous woman in San Francisco immigration court today spoke neither English nor Spanish. She seemed not to understand the proceedings, & even DHS agreed to postpone her hearing.

It didn't matter. ICE agents arrested her in the hallway anyway.

Breaking News: A Trump administration settlement proposal demands more than $1 billion from UCLA. It calls for the payout to contribute to a claims fund that would compensate victims of civil rights violations after a pro-Palestinian protest on campus.
Trump Wants U.C.L.A. to Pay $1 Billion to Restore Its Research Funding
The Trump administration has ended about $500 million for the Los Angeles-based university. The president said he wanted nearly double that to restart the flow of funds.

200 days in, checking in on HHMI funding opportunities:

Freeman Hrabowski Scholars Program - not accepting applications

Hanna H. Gray Fellows Program - not accepting applications

This is not some small foundation -- HHMI has a $24 billion endowment. It is the world's 2nd richest biomedical research foundation.

If any funder can double down on their support for science right now, it's HHMI. But they are doing the opposite.
