The two anti-AI arguments I hear a ton are the ethics one and the idea that it's utterly useless and anyone who finds value in it is deluding themselves. The former holds water, but I've heard of enough cases where people find AI really helpful that the latter seems like nonsense.

In conclusion, we should negotiate! But Putin won't be won over through superior argument or an appeal to higher morals. This is about power. Ukrainians will have to make painful concessions either way, but there's a difference between that and outright surrender

Ukrainians have to decide what's best for Ukrainians. But for us, the least bad option is the same it's always been: Cripple the Russian economy and empower Ukraine's military to inflict more and more pain on Moscow

The whole "people say we can't talk to Putin" thing increasingly feels like a straw man. Is anyone here actually opposed to negotiations? Western leaders practically begged Putin not to invade. Zelensky would sit down with Putin tomorrow if he agreed to meet outside Russia

Light after darkness: In the Fürstenfeldbrück DP camp, two children and Yaakov Goldman, the chief rabbi of the U.S. Army in Europe, join to light the third candle on the hanukkiah. It is 1945, and they are celebrating Hanukkah for the first time since the Holocaust.

I love this logic: "abstracts are often badly written => let's use LLMs to write more badly written abstracts"
Instead of, you know: "abstracts are often badly written => let's improve our review process to make the authors write better abstracts"

* They are intended to describe the contents of the paper as presented, including scope and limitations. Author abstracts, understandably, often emphasize positive contributions. They are often writing for the reviewer and trying “sell” their work in a constrained space.

Very sad that I felt I had no choice but to resign from The Infinite Monkey Cage - a victory for the transphobes and other bigots - I did it because so much of the media has chosen to believe the kind and empathetic people are a fiction - they are real and so often unrepresented.

This is the saddest day of my professional life.
Today is not only the final recording of the latest series of The Infinite Monkey Cage, it is my last ever Monkey Cage.
I never thought that I would have to leave the show. I always imagined going on until | dropped dead under the studio lights due to a brain aneurysm caused by my final attempt to understand notions of quantum gravity or the shock of being told about fly maggot infestations in the sacks of macaque monkeys.
I resigned in September, after sixteen years of dedication to the show,
A show that I named and helped develop over all those years.
Unfortunately, my opinions outside the BBC have been considered problematic for sometime, whether it has been voicing support for the trans community, criticism of Donald Trump, numerous other outlandish opinions, including once gently criticising Stephen Fry.
These things were considered to conflict with being a freelance BBC science presenter

In a recent meeting where BBC Studio executives again voiced problems with me, I realised my choices.
Obedience and being quieter to remain making Monkey Cage, or 'Resign and have the freedom to speak out against what I believe are injustices'.
•
I chose the latter.
It broke my heart.
I love this show and I love the audience, and it is because of the audience in particular, that this decision was so difficult to make.
I kept thinking about all the extremist voices promoting hate and division. They are being given so many platforms, while voices that represent kindness, open mindedness, empathy seem to be scarcer and scarcer.
I felt I couldn't pamper myself with the luxury of silence.
One of my many privileges is that I am able to resign and I can speak out even if it is to the detriment of my career.

I have thought a lot about my heroes, Sinead O Connor, James Baldwin, Audre Lorde, and so many more.
I think of Sinead's words, "the job of an artist is to be themselves at any cost".
James Baldwin said prejudice was really just a word for cowardice.
Audre Lorde, viewing her life, wrote that her only regrets were her silences.
I think of my father as I resign, he brought me up to believe in fairness , justice and kindness.
Though my heart is broken, it is also full of fire.
I apologise to our incredible listeners for my departure, your love of the show means a great deal.
I am so sorry to let you down.
I hope that you can understand my reasoning.
I have to accept that I am not what the current
BBC expects of their freelance presenters.

Despite this I should add that I have always worked far more than my contracted hours to try and ensure the show was always the best it could be, as well as making myself accessible and responsive to the audience wherever and whenever I met them. Every night, we have recorded, I have been filled with determination to make the best show possible. This was not
"just a job"
I hope that with my departure I can be a better ally to the LGBTQ community, to the neurodivergent community, to activists fighting against those who aim to brutalise society, to those currently in prison on hunger strike, and to all those who fight for a more inclusive world.
From many conversations, I know there are many Monkey Cage listeners who support these communities and activists too.
The strawberry is dead.
Long live the strawberry. B

I'd prefer the second one - the first one feels a bit too cluttered for me (in particular, all the UI elements are kind of distracting).

Though, either is a nice change from the usual TikZ drawings one sees in every talk on this subject!

I wish I didn’t have to share this. But the BBC has decided to censor my first Reith Lecture.

They deleted the line in which I describe Donald Trump as “the most openly corrupt president in American history.” /1

Der Denkfehler so vieler Leute, von Ezra Klein bis Sam Harris: "Die Leute wählen rechtsradikal, dann müssen wir halt alle etwas rechtsradikaler werden, um den Status Quo halbwegs zu konservieren."
Gewählt wird meist aber nicht FÜR Rechtsradikalismus, sondern in erster Linie GEGEN den Status Quo.

Math has publication fraud, too.

For a long time, mathematicians thought that as long as they keep away from predatory journals or paper mills, the problem does not affect them. This turned out to be wrong.

When a typo in the abstract makes you more likely to read the paper :-)

The picture consists of two parts:
On the top a screenshot from a paper on arxiv. The title reads "Spectral extrema of graphs of given even size forbidding H(4,3)", the abstract below starts with the following text "A graph is sad to be H-free if it does not contain H..."
Below is a handdrawn image with the title "Without H everything is sad" and a drawing of a graph resembling a sad smiley face. Next to it is an arrow pointing to it with the text "grap(h) sad"

In geometry we call something 'generic' if there is nothing special about the situation. E.g, 3 generic points in the plane don't lie on a single straight line.

If you prove a theorem for the generic situation, you have proved it in a special case only because you disregarded the special cases. 🤯
