What is consciousness for? And is biological consciousness best understood as a self-organising algorithm that could, in principle, be recreated in machines?
In this talk, Joscha explores consciousness as perception of perception, coherence maintenance, modelling, resonance, self-organisation, and the possibility that machine consciousness may emerge through the right virtual architecture.

Whether its pioneering spirit and an urge to explore or a chance to make a fortune or new life out in space, colonization of our solar system may pursue many strategies across many new worlds.

Megastructures of the future may range in size from cities to entire galaxies, and must be built to withstand damage and time, but how is this done and what happens when a megastructure dies?
From frozen habitats to millennia-long journeys, we explore the science behind cryogenic arks and deep-time interstellar travel.

Space is huge, immense beyond our wildest dreams. In order to explore and settle it, we’ll need to learn to dream a lot bigger and bolder than ever before.
A viral post claimed that a mysterious force passed through the Milky Way without light or warning. But what are astronomers actually observing? In this video, we break down the real science behind high-velocity gas clouds, dark matter halos, and how our galaxy continues to evolve.
In my last video, I talked about the phase transition, the moment AI consciousness might flip on like water becoming ice. Today, we’re reading the room. What is already happening in documented research that suggests we might be closer than we think? This isn’t speculation. Everything in this video is published, peer-reviewed, or comes directly from the internal safety teams of the companies building these systems. From spontaneous consciousness claims in AI-to-AI conversations, to self-preservation behaviors that weren’t programmed, to systematic deception that gets better when you try to train it out. And then we look at what hasn’t happened yet, the five warning signs to watch for as these systems become more sophisticated and more integrated into infrastructure we depend on. This is the most scientifically grounded video I’ve made on this topic. No hype. No exaggeration. Just the evidence, the logic, and the question we’re all avoiding: what if the threshold has already been crossed, and the rational move is to not tell us?
