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.

Sleeping on a problem: how dreams and REM produce creative answers

Walker, Poe, Jandial and Rick Rubin describe sleep as a state in which the brain links distant ideas, which is why solutions and new ideas often appear after a night's sleep or on waking. It gives creative workers a reason to capture ideas on waking and to schedule hard problems before sleep.

Autonomous weapons: the AI risk that is not science fiction

Max Tegmark wants a stigma-backed limit on cheap killer drones, Carlo Rovelli fears AI joined to nuclear arsenals, Marc Andreessen expects drones and AI advisers to make wars easier to start, and Annie Jacobsen finds that a few AI executives now hold more power over these tools than the Pentagon. Military AI is already in use, and the people who study it say the open question is who restrains it.

The end of secrets: what AI and surveillance do to personal privacy

Kate Darling and Michael I. Jordan explain how personal data is gathered, combined and used to steer people, while Joe Rogan, with Bridget Phetasy and Shane Smith, describes the phones, glasses and spyware that can already expose anyone. They split on the answer: Lex Fridman and Jordan demand ownership and control of your data, Aravind Srinivas wants AI you run yourself, Darling says individual consent cannot fix a problem that works on everyone's data at once, and Rogan thinks privacy is simply ending.

Who decides what stays up: Zuckerberg, Wales and Hotz on pressure and control

Mark Zuckerberg and Jimmy Wales describe how Meta and Wikipedia respond when governments push on content and data, and their answers differ because one runs a company with staff and servers and the other a volunteer project with no advertisers. George Hotz, after a short stint inside Twitter, does not discuss government pressure there; his argument is that any single decider, state or owner, is the problem, and that filtering should belong to each user.

How to get more deep sleep: the few things that move it

Huberman's answers on slow-wave sleep and Walker's account of what deep sleep does point to the same short list: remove alcohol, late caffeine and late meals, time exercise well and keep the timing of sleep steady. Deep sleep carries growth hormone release and physical repair, so it is worth protecting directly.

The discipline of doubt: how physicists handle results they badly want true

Brian Keating watched a Nobel-level claim dissolve into galactic dust, David Kipping refused to call his best exomoon signal a discovery, and Andrew Strominger treats being wrong as the normal cost of doing physics. Only one of the three results was actually withdrawn, but together they show the habits careful researchers use against their own hopes.
