I’m sick of it. While I must confess to having poured more than a few buckets into the AI doom reservoir, enough is enough. If you’re as saturated with the AI Apocalypse as I am, this clip from my conversation with Yann LeCun (Yann LeCun) is a powerful antidote. I don’t agree with him on everything. That’s the point. But what can you say to refute him? cc Dr. Roman Yampolskiy Emad Max Tegmark

In recent days, multiple Erdős problems have been solved by GPT-5.2 Pro, with solutions accepted by Terence Tao. This is not a gimmick—it's a qualitative shift. Erdős problems lie at the core of additive combinatorics, extremal graph theory, and probabilistic methods—problems that resist brute force and demand structural insight. Many have endured decades of expert scrutiny. Acceptance matters more than authorship. Tao doesn't rubber-stamp ideas; he rigorously tests logic, generality, and novelty. If a proof clears that hurdle, the system didn't merely recombine known lemmas—it explored a true mathematical search space. This means AI has crossed a threshold: from assisting mathematics to participating in it by proposing nontrivial arguments, uncovering hidden structures, and resolving problems humans value—without a predefined solution path. Importantly, this doesn't diminish human mathematicians. It reshapes the field's topology. Just as symbolic algebra systems amplified rather than replaced math, AI now seems poised to expand the frontier itself. If these claims hold, recent days may mark the lift-off for AI-driven science: not flashy demos, but quiet validation by the world's toughest referees. We should remain skeptical, careful, and precise—yet honest about the implications. Something fundamental may have changed. Here's a five-minute video with Terry explaining these problems and meeting the man himself:

Sam Harris on why consciousness is more certain than the universe — and why free will is a different problem entirely Pulling out a clip from my conversation with Sam Harris (Making Sense Podcast) where he draws an asymmetry I think is worth sitting with. His claim: consciousness is the one thing in the universe that can't be an illusion — even more certain than physics. We could be brains in vats, in the matrix, on an alien supercomputer. None of it changes the fact that something seems to be happening. That seeming IS consciousness. Free will? Different story. Sam argues it's not just illusory but incoherent — provably so, regardless of how you tune determinism vs quantum indeterminism. He agrees with Sapolsky on the conclusion but adds a unique contribution on the experience of free will itself. Curious what the community thinks. Does the consciousness-as-bedrock argument hold under closer inspection, or is it just Descartes in new clothing?

The Quantum Theory No One Dares Explain! David Deutsch Timestamp: 02:15 – David Deutsch introduces the idea that infinity is not just a mathematical abstraction but a physical reality. 06:42 – He emphasizes that understanding infinity is central to progress in both science and philosophy. 11:03 – Discussion on how infinity challenges human intuition and traditional explanations. 18:29 – Deutsch argues that good explanations must account for infinity, not avoid it. 23:51 – He contrasts finite vs. infinite models of the universe. 30:14 – Infinity as an unavoidable aspect of quantum mechanics and the multiverse. 37:40 – Practical implications: infinity changes how we view knowledge, discovery, and human progress. 45:22 – He warns against simplistic or “bad” explanations that ignore infinite possibilities. 53:09 – Closing: infinity should be embraced as part of reality, not feared or reduced.
