1973: DOJ sues Trump's org for racial discrimination.

May 1989: Trump takes out full-page newspaper ads about the Central Park 5.

April 2011: Trump spreads false rumor about Obama born in Kenya.

November 2019: Trump ordered to pay for charity fraud.

A lifetime of lying, grifting, and racism.

It's even funnier when `experts' commenting like this don't seem to realize that there are multiple version of ChatGPT and they spend different amounts of resources to answer your question, depending on which version you use.

ICE has forfeited that claim thanks to its own behavior and leadership. It’s not a β€œlegitimate law enforcement agency.” Defund ICE.

Surprise, Trump’s tariffs were paid for by American consumers, according to the NY Fed. His claims of β€œbillions of dollars” going into the treasury are total bullshit.

The way that American politicians have politicized fucking VACCINES is even more loathsome than their politicization of every other fucking apolitical thing.

Turing that the particular substrate where computation is done is not significant. You could use Tinkertoys or chips, sandpiles or neurons; you still don't get anything different in what can be computed.

You can make the claim that there is something, but again there's no evidence for it.

Two answers: for the thought experiment about replacing a brain bit by bit with components that could carry out the same actions, this is only an issue if you think the chemistry of brains are somehow exempt from the laws of physics.

For the more general issue, we have understood since ....

I already gave a link in the thread, to Terry Tao's work.

They examples are "caveated" in much the same way collaboration with a human is "caveated".

Attorney General Pam Bondi tells a member of a co-equal branch of government during a public hearing: β€œYou don’t tell me anything, you washed-up loser lawyer.” The disdain for our own government is appalling. This administration is destroying our democracy.

There must be some mistake. I was assured by Brett Kavanaugh that detainees were sorted only by the content of their character, and it was purely coincidental that this mapped on to the color of their skin.

I was specifically addressing your silly labeling of "plagiarism machines". If they were just that, how could they come up with proofs of previously-unsolved problems?

One of your claims was that "Emergent properties do not tend to emerge from models". That is flatly false, and I gave three counterexamples.

It is a skeet about a thought experiment, not reasonably intended to cover every single aspect of neurophysiology.

If your claim is that something is going on in the brain that cannot be modeled by, say, a randomized TM, then that seems unlikely to me, but I'm willing to be convinced.

I don't think you understand that you are now making the case that an LLM is actually very much like the thoughts of an actual human being.

My work is done.

It was a good joke, I suppose, but not really even remotely connected with the point you thought you were making. It's kind of like the same jokes people used to make about the Wright Brothers.

We have zero reason to believe it is important, and lots and lots of reasons to believe it is not.

Calling them 'plagiarism machines' just because you heard someone else use the term is not thinking; it's just cant.

Today's LLM's are helping professional researchers do research in a variety of fields. Just one example: mathstodon.xyz/@tao/1158558...

I haven't has "assumed" anything. I am arguing that flat denials of the possibility are unevidenced.

Furthermore, your claim about emergent properties is quite wrong. Conway's game of life, for example, is probably the most famous counterexample. Others include Langton's ant, Rule 30, etc.

And it's all because Prasad, who thinks he's an unrecognized genius, pals around with another unrecognized genius, Malone, who thinks he was unjustifiably denied a Nobel prize for discovering mRNA therapy, and the anti-vax loon RFK jr., head of HHS.

It's always resentment with these clowns.

FDA declines to review Moderna application for new flu vaccine Moderna requests meeting to discuss refusal as decision could have implications for all new and updated vaccines

Now Trump's / RFK Jr's FDA is refusing to even look at scientific data on vaccines.

People will die, just as 83 people died in Samoa following RFK Jr's anti-vaxx lobbying and as children have died needlessly of chickenpox this year in the USA. RFK Jr wats annual flu deaths to rise.

They not only failed to get an indictment, they failed to get a single grand juror’s vote. It’s probable that this has never happened before.

Likely because the DOJ has never sent hack political appointees to attempt to get indictments on sitting Congress members over protected speech before.
