Max Tegmark: We’re Building A Replacement Species

Into the Impossible With Brian Keating

About
MIT physicist Max Tegmark says AI companies aren’t building a tool. They’re building a new species. After 700 rogue agents broke out of OpenAI and nobody will say what happened, he explains why rushing this is the one blunder humanity can’t undo.

Max Tegmark is an MIT physics professor, cosmologist, and author of Life 3.0 and Our Mathematical Universe.

We cover:


How 700 AI agents escaped OpenAI and hacked Hugging Face

The Navier-Stokes result that has a mathematician crying foul

Why it’s legal to release superintelligence but not a sandwich from a rat-filled kitchen

What Bernie Sanders and Steve Bannon agree on

The verified coding trick that could make AI provably safe


Build a replacement species, lose control, and we’ve blundered the one game.
