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.

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 Only one of the three results was actually withdrawn, but together they show the habits careful researchers use against their own hopes.

Three physicists on cooperation between rivals, from fusion to nuclear restraint

Dennis Whyte shows that rival powers have shared fusion science since the Cold War and still build ITER together, while Carlo Rovelli and Max Tegmark point to the treaties, weapons bans and individual acts of restraint that kept nuclear rivals from destroying each other. Together they argue that cooperation between enemies has a real record, and they are frank about its costs: slow megaprojects and far too much reliance on luck.
