One popular objection to AI concerns is to declare that LLMs can never be AGI. You need a “new paradigm”. Therefore, AGI is so far in the future that it’s not worth worrying about.
A common counterargument is to claim that no, LLMs can become AGI. But even without that counterargument, I think the “therefore” fails on its own terms. The key question is: how much of a new paradigm do we need?
The landmark discoveries on the road to modern LLMs are something like:
1950s: Neural networks
1967: Multi-layer perceptron
2010: Modern deep learning
2017: Transformer, LLM
2022: RLHF, chatbots
2024: Chain of thought / test-time compute
We can think of this as an “evolutionary tree”, where a given LLM (let’s say Claude Opus 4.7) shares a recent “common ancestor” with all other chatbots, and only a very distant “common ancestor” with everything else descended from the multi-layer perceptron. If AGI needs a “new paradigm”, what common ancestor can we expect AGI and LLMs to share?

Uncovering nature’s secrets is no easy task. The daily life of a scientist is often grueling, frustrating, and—perhaps surprisingly—boring as they repeat experiments over and over. Here’s where 
The equations that govern black holes were true before there were black holes. That claim is hotly contested, and cuts through one of the deepest fault lines in the philosophy of mathematics. On one side are those who hold that mathematical structures, including well-established principles and basic geometric shapes like the tetrahedron, exist independently of human thought – not as a language we invented to describe reality, but rather as the substrate of reality itself. On the other side of the debate are those who argue that mathematics is the product of human labours, imposed on a world that would be wholly indifferent to it were we not here.
Pope Leo XIV will personally present his first encyclical, Magnifica Humanitas, on 25 May at the Vatican’s Synod Hall, and one of the speakers alongside him will be Christopher Olah, co-founder of Anthropic. The Vatican announced the details on Monday, confirming that the document will address the protection of human dignity in the age of artificial intelligence and that the pope will break with tradition by presenting it himself rather than delegating the task to cardinals and press officials.
For nearly 80 years, mathematicians have studied a deceptively simple question: if you place

“The duty of every revolutionary is to make the revolution.” Every New Leftist in the late 1960s was familiar with that axiom, attributed to Fidel Castro, and most took it to heart. Yet in a leaderless movement, there were numerous ways to comply. Some sought to advance the revolution with marches demanding the U.S. pull out of Indochina right away, allowing the indigenous communists to win. Others set up women’s clinics, radical bookshops and food co-ops, or moved into rural and urban communes. Such institutions “prefigured” those that radicals longed to build in the ashes of the evil system they aimed to destroy. But the jefe of Cuban communism and his bosom comrade Che Guevara had made their revolution with guns and bombs. And they were urging leftists around the world, in Guevara’s words, to “create two, three, many Vietnams”—wars against imperialism—before Bolivian troops captured and murdered the guerilla icon in 1967.
Mira Nair is used to getting attention. She has carved a unique perch as a filmmaker by focusing her lens on the intimate social and cultural lives of Indians. But when she began shooting her latest film, based on the unconventional life of the early 20th-century Hungarian-Indian painter Amrita Sher-Gil, she noticed that the nature of people’s attention had changed. More people started coming up to Ms. Nair, she said, recognizing her as the mother of Zohran Mamdani, the mayor of New York City. Some, including young artists on her own film set, told her that his political views resonated with them.
In late 2024, philanthropists interested in wildlife conservation got an intriguing offer: Donate to a new fund that would provide small grants to young researchers seeking to discover new kinds of tropical animals, and you could help name the new species. The 
In 1976, Peter Frampton was a guitar player who was respected among his more popular peers despite having enjoyed no commercial success. He had only a small following in his native Britain and in a couple of American cities—and then with lightning speed, he became the biggest star on the planet. The live album Frampton Comes Alive! (1976) brought him fame and commercial success, but, as he was later to recall in his 2024 Rock and Roll Hall of Fame induction 
A group of 38 prominent scientists from around the world — including 16 members of national academies and two Nobel Laureates — called for a halt on the creation of of a novel synthetic bacteria that, if realized and accidentally leaked into the environment, could dodge typical ecological checks and lead to an uncontrollable spread of deadly infection that posed a threat not just to humans but to many forms of life upon our earth and in our oceans, from the animal to the vegetal, from the micro to the macro. They provided a robust
