Working on climate change is skipping like a stone over sentences like "A new study analysing 49 years of data from 20 sites indicated carbon is being emitted because trees are dying and decaying faster than they can be replaced." every day while people with power do everything to make it worse.
Australia's tropical trees emit more carbon than they absorb: study
Climate change is killing trees faster than they can be replaced leading to greater carbon emissions, according to a new study.

Even assuming one accepts LLMs as a specific, valid 'tool', tool-driven learning is a sure way to be Left Behind. Individual tools are inevitably superseded. Instead, foster the mind: the ultimate tool for any job. A well-nourished mind can always adapt to the task at hand.

Lots of people with money who want to make more are telling you this is a tool you have to learn or you'll be Left Behind but as with all tools, you can use your own brain and experience to decide if it's a thing that helps you do your job better and a thing you think is ethical.

I think the idea of "cancel culture" persists mainly because it conveniently is some outside force acting on someone rather than them torching their reputation all on their own

I have been to two No Kings protests and they are filled with normies and people with funny signs and families and they are just the most wholesome protests imaginable

that's all people are going to see, man - their friends and neighbors out there saying we don't want this

Johnson: "We call it the Hate America Rally that will happen Saturday. Let's see who shows up for that. I bet you you'll see Hamas supporters, I bet you'll see antifa types, I bet you'll see Marxists on full display, people who don't want to stand and defend the foundational truths of this republic"

Misinformation and disinformation now pose some of the biggest global risks to democracy and public trust. In the latest PsychTalks episode, A/Prof Piers Howe explains why it's important to stay informed, think critically and understand the science behind persuasion.

I think that often the people with these blindspots are either afflicted by motivated cognition (they WANT to believe) or pay no attention to the role of power and money as possible motivations or influences on what is being said, by whom, to what audience, etc.

Same here. I am not the most interpersonally perspicacious person, so when something is blisteringly obvious to ME and yet other seemingly sophisticated thinkers buy into the bullshit, it's truly baffling.

If there’s one thing about the last decade that has truly done my head in, it’s seeing how many people - including many very well educated people with power - appear to be totally incapable of spotting an obvious bullshitter in the act of bullshitting.
airwindows.com
How do people not SEE the extent to which this guy is an utter bullshitter? Is this some kind of autistic soul-read thing I'm manifesting? I don't understand how people aren't getting constant red flags from this guy. Every picture just trumpets bullshitter, he is like a parody of a normie-fooler.

It’s funny how black people are expected to reach across the aisle to voters like these, while no one ever expects them to reach across the aisle to black people. Amazing who gets to be human, and who doesn’t.

POLITICO: “.. They referred to Black people as monkeys and ‘the watermelon people’ and mused about putting their political opponents in gas chambers. They talked about raping their enemies .. and lauded Republicans who they believed support slavery.

“Things are always happening that have the potential to change you.” 🔥

"You make the best of it all and hope you can help make it a little better for the gurl after you."

- Miss Major, 2023 💔
One of the things I hear with some younger trans people I know is they feel, "I'm gonna get this surgery, and I'm gonna learn that way of speaking, and I'm gonna be done." You're never done. If you're a straight, cisgender person, you're never done. Things are always happening that have the potential to change you. So all I am today is not who I'm gonna be tomorrow, because of the things that happened to me today and later tonight. People forget that. "Oh, after I transition, I'm gonna be through." Well, good luck with that. 'Cause if you're through, then it's time to leave, you know, and I don't wanna go anywhere yet.
I'm in my seventies. Why didn't I stop? Number one is community. My gurls. I've had moments of thinking about stopping, but I didn't. I made sure I would step back, reju- venate myself, and then got back out there, and that's how you make a way. Our stories are not all the same, but the destination is: to get some place where we have some peace and harmony, and we can be at ease with ourselves and the people around us. You make the best of it all and hope you can help make it a little better for the gurl after you.

IMHO, LLMs will be an economic negative for years.

They'll do a worse job than humans,

but will still replace humans because they're cheaper for employers,

but really they're costlier, it's just that lots of costs get externalized to society by our horrible energy/tax policies.

Lose-lose-lose.

anyone else notice that the west took a turn for the worse once the concept of signaling one’s own social virtue became derogatory, almost as if cynically deriding all displays of charity and good will is indicative of a deeply cynical and nihilistic society capable of collaborating in genocide

her advocacy for Palestinians doesn't bother me nearly as much as she is so desperately doing all this as an actual act of transparent virtue signaling, to fill the absence she has in depth of character

A surprisingly hopeful perspective from a reporter who asked random folks on the east coast how they were doing, learned we’re all having a really bad time, and chose to highlight the shared humanity in that.

You would not fire these people—including the staff of the hugely, HUGELY important 'Morbidity and Mortality Weekly Report'—if you cared at all about public health, if you wanted people to live.

And you would not let your thuggish henchmen fire people like this if you were a responsible president.

New from me at Cato: I go through the numerous and massive First Amendment and academic-freedom violations of Trump's proffered "compact" with universities and then talk about the mechanism by which it would be enforced, by way of what I describe as a "retroactive push-button guillotine."
