We often speculate that the reason we can’t hear aliens civilizations is because our SETI efforts (the Search for Extraterrestrial Intelligence) relies on radio and telescopes to weak to hear them. But how plausible is that? and what would it tell us about our own future?

The Zoo Hypothesis is a Fermi Paradox solution that assumes extraterrestrial civilizations can’t be detected by our SETI efforts because they keep our whole world in an Alien Zoo.

Many seek a path to enlightenment through study and meditation, but what does science tell us about transcendence? And could entire civilizations seek to leave this reality behind?

Connor Leahy joins the podcast to discuss the motivations of AGI corporations, how modern AI is “grown”, the need for a science of intelligence, the effects of AI on work, the radical implications of superintelligence, open-source AI, and what you might be able to do about all of this. Here’s the document we discuss in the episode: https://www.thecompendium.ai Timestamps: 00:00 The Compendium 15:25 The motivations of AGI corps 31:17 AI is grown, not written 52:59 A science of intelligence 01:07:50 Jobs, work, and AGI 01:23:19 Superintelligence 01:37:42 Open-source AI 01:45:07 What can we do?

It’s a mission that is less a nostalgic yearning for a prehistoric past than it is a solution to combat climate change, the company’s founders have said. By reintroducing mammoths to Arctic environments, they hope to rejuvenate grasslands and reduce permafrost thaw—a major source of methane emissions.

The potential ripple effects of such an ecological intervention have raised profound ethical and scientific questions but have nonetheless captivated researchers, investors and the public alike.

Colossal Bioscience’s approach to de-extinction is rooted in cutting-edge advances in genetic engineering and synthetic biology.

In a universe stretched thin by eons, where stars have long faded and even atoms face their end, a single question remains: can intelligence find a way to outlast time itself?

Cosmic Radiation: A Supernova’s Deadly Reach

Around 2.6 million years ago, a supernova erupted just 150 light-years from Earth, creating a dazzling display in the sky. But its most significant impact may have occurred years later when a wave of cosmic radiation reached Earth, triggering a marine extinction event. Researchers led by Adrian Melott of the University of Kansas propose that this cosmic catastrophe may have contributed to the disappearance of marine giants, including the Megalodon. Their findings were published in Astrobiology.

Vector Institute’s Remarkable 2024 | Geoffrey Hinton — Will Digital Intelligence Replace Biological Intelligence?

In this profound keynote, Vector co-founder Geoffrey Hinton explores the philosophical implications of artificial intelligence and its potential to surpass human intelligence. Drawing from decades of expertise, Hinton shares his growing concerns about AI’s existential risks while examining fundamental questions about consciousness, understanding, and the nature of intelligence itself.

Geoffrey Hinton is one of the founding fathers of deep learning and artificial neural networks. He was a Vice President and Engineering Fellow at Google until 2023 and is Professor Emeritus at the University of Toronto. In 2024 Hinton was awarded the Nobel Prize in Physics.

Key Topics Covered:
• The distinction between digital and analog computation in AI
• Understanding consciousness and subjective experience in AI systems.
• Evolution of language models and their capabilities.
• Existential risks and challenges of AI development.

Timeline:
00:00 — Introduction.
03:35 — Digital vs. Analog Computation.
14:55 — Large Language Models and Understanding.
27:15 — Super Intelligence and Control.
34:15 — Consciousness and Subjective Experience.
41:35 — Q\&A Session.

Remarkable 2025 is coming, subscribe to our newsletter.

If Earth’s life survives the Anthropocene, it will eventually face another existential threat from space.

As the Sun brightens with age, it will inevitably interfere with our planet’s finicky carbon cycle, triggering a depletion of atmospheric carbon dioxide to the point where plants will starve.

Luckily, this won’t happen until at least 1.6 billion years from now, suggests new research from University of Chicago geophysicist RJ Graham and colleagues. That potentially doubles the projected lifespan of Earth’s plants and animals.
