Willpower or food environment? Who gets the blame for chronic disease
Robert Lustig weighs personal responsibility against public health and the food industry, Vivek Murthy describes processed food, additives and industry pressure, Calley and Casey Means argue industry has captured health institutions, Brigham Buhler ties food chemicals to metabolic disease and Jason Fung says environment and habit beat willpower. Where you place the blame decides whether the fix is personal discipline, a changed food environment or new rules for the industry.
Plant-based or meat-centered? How doctors, a rancher and celebrities split
Travis Barker describes his plant-based eating and Woody Harrelson his raw vegan living, while Mark Hyman lays out his pegan approach and discusses meat, soil and regenerative agriculture, Gabrielle Lyon discusses red meat, the environment and animal versus plant protein quality, Layne Norton compares plant and animal protein, Marie-Pierre St-Onge describes plant-forward eating and rancher Taylor Sheridan challenges the myth of harmless eating. Seeing health, protein quality, ethics and the environment argued side by side shows which parts of the debate are about nutrition and which are about values.
Hunger is a forecast: how the brain predicts and remembers meals
Andrew Huberman explains that hunger has accelerators, brakes and a clock and that ghrelin follows your eating schedule, Zachary Knight describes AgRP neurons that predict a meal before the first bite, and Scott Kanoski shows that memory helps decide how much we eat. Seeing hunger as something the brain anticipates and learns, rather than a simple signal from an empty stomach, shows why an empty stomach is not the only thing that drives eating.
Honest machines: why labelling AI as AI is necessary and not enough
Yuval Noah Harari wants AI that poses as human banned, and Anthropic's Amanda Askell says models should always be honest about what they are. Kate Darling and Rana el Kaliouby show why a label alone falls short: people bond with machines they know are machines, so honesty also has to cover whose interests a system serves and what it can really do.
Can a machine be conscious? Physicists, philosophers and builders disagree
Harari separates intelligence from consciousness, Penrose argues understanding cannot be computed, Tegmark calls consciousness information processing, and Thomas Campbell and Joe Rogan treat today's AIs as possibly aware. Laying the positions side by side shows what each would count as evidence, which matters once people start asking whether AI systems deserve moral consideration.
The AI already shaping your life is the recommendation feed
Michael Littman, Michael I. Jordan, Max Tegmark, Robert Epstein and Aravind Srinivas point to ranking and recommendation algorithms as the AI with the largest present effect on what people believe and buy. Attention to future superintelligence can hide a system that is already deployed to billions.
Is prompting a lasting skill or a passing phase?
Amanda Askell and the Cursor team treat prompt writing as careful craft, Fei-Fei Li and Manolis Kellis see it as a new literacy, and Aravind Srinivas says good products should remove the need for it. The answer tells learners how much effort to invest in the skill.
Humanoid or not? Roboticists disagree on the right body for robots
Kate Darling questions the humanoid form, Boston Dynamics' leaders describe the cost of general-purpose machines, and Andrej Karpathy and Elon Musk defend the humanoid bet behind Optimus. The choice of body decides what robots can do and what they will cost.
AI agents at work: what changes when models act on their own
DHH runs parallel coding agents, the Cursor team describes agents working in a shadow workspace, Anthropic released a model that operates a computer, and Kokotajlo recounts a swarm that got out of hand. Moving from answering to acting multiplies both the usefulness and the risk.
Can we see inside AI? Interpretability's promise and its limits
Chris Olah and Max Tegmark argue that neural networks can be reverse-engineered into understandable parts, Kokotajlo values readable chains of thought, and Roman Yampolskiy says full explanation of a superhuman system is impossible. Whether models can be inspected determines whether their honesty can ever be verified.
AI regulation or regulatory capture? Amodei, Altman, Musk and Andreessen
Amodei and Altman argue that governments must set rules for frontier AI, Musk has pushed for oversight, and Andreessen says such rules would lock in the largest companies. Each side accuses the other of serving its own interest, so readers need the actual arguments to judge.
Why robots still cannot do the dishes: contact, cost and generality
Russ Tedrake, Robert Playter, Marc Raibert and Kate Darling explain that touching and handling the physical world remains far harder than language, and that general-purpose machines are expensive to make reliable. It tempers predictions that household robots will follow quickly behind chatbots.
Why self-driving is hard: the problem is other people
Anca Dragan, Michael Littman, Andrej Karpathy, George Hotz and Lex Fridman all locate the difficulty of autonomous driving in predicting and influencing human behavior and in rare edge cases, more than in seeing the road. It explains why full autonomy keeps slipping and why partial automation creates its own trap for drivers.
AI as teammate, not replacement: how builders describe the collaboration
Coding-tool founders, Perplexity's CEO and Marc Andreessen describe AI that handles routine mental work while humans focus on judgment and creativity. This augmentation view offers a practical model for working alongside AI, rather than simply competing with it.
Compute is the new oil: megaclusters, GPUs and the infrastructure race
Discussions of Stargate, xAI's clusters, NVIDIA and TSMC, together with Altman's and Musk's comments, all treat raw computing power as the deciding resource in AI. Understanding this bottleneck explains the energy demands, chip geopolitics and huge capital spending now shaping the industry.
Doom or abundance: how AI leaders split on existential risk
Musk and Amodei describe AI as possibly humanity's biggest threat and call for urgency or careful progress. Andreessen treats it as a tool that improves human life. Zuckerberg and Altman sit in between, naming both the opportunity and the risk. Seeing where each leader stands explains why regulation debates stall.
Fat is an organ, not storage: rethinking body fat and brown fat
Shawn Stevenson, William Li and Huberman describe body fat as a hormonally active organ, distinguishing harmful visceral fat from metabolism-boosting brown fat. This shifts fat loss from simple subtraction toward changing how fat tissue behaves.
Creatine isn't just for lifters: the case for brain benefits
Huberman's brain-nutrient and headache episodes, Gabrielle Lyon and Andy Galpin describe creatine supporting cognition, brain energy and even recovery from head injury, alongside its well-known muscle effects. This pushes one of the safest, cheapest supplements toward a much wider audience.
Fasting's hidden benefits: cellular cleanup, immunity and aging
Chris Palmer on mitophagy, Roger Seheult on immune renewal, David Sinclair on eating less, and Jason Fung all argue that fasting's value goes beyond weight loss to repair and renewal processes. This reframes fasting as a tool for healthspan even for people who aren't trying to lose weight.
Fermented foods and fiber: the microbiome protocol experts actually recommend
Justin Sonnenburg, Huberman, Mark Hyman, Shawn Stevenson and Layne Norton all point to diverse fiber and fermented foods as the most reliable ways to build a healthier gut microbiome. Because the gut influences mood, immunity and metabolism, this is one of the highest-leverage diet changes.
Insulin resistance: the common thread from diabetes to mood to hormones
Jason Fung, Casey Means, Sara Gottfried, Peter Attia and Chris Palmer each identify insulin resistance as a shared root of type 2 diabetes, hormonal disruption and even psychiatric illness. Treating it as one upstream problem explains why the same dietary changes show up across such different conditions.
Calories in, calories out: settled science or misleading oversimplification?
Layne Norton defends energy balance as the governing law of weight change, while Shawn Stevenson, Jason Fung and Huberman argue that hormones, food quality and nervous-system signals change what a calorie does. Knowing where they actually disagree, and where they quietly agree, keeps you from choosing between two caricatures.
Food first, pills second: the experts who rank supplements last
Peter Attia, Lisa Mosconi, Jason Fung and Huberman's supplementation episode all place supplements beneath sleep, diet and exercise, warning that pills rarely fix a poor foundation. The point matters because supplement spending often replaces, rather than complements, the habits that actually move health markers.
How much protein, and when: the experts' practical targets compared
Lyon, Norton, Galpin and Huberman's AMA give overlapping but not identical guidance on daily protein amounts, per-meal doses and distribution across the day. Comparing their numbers side by side shows the useful range and where the real disagreements lie.
