MIT physicist Max Tegmark says Yann LeCun was simply wrong about how fast AI would advance, and that LeCun’s faith in human nature is the bigger blind spot. If one angry person can now do what once took an army, “provably safe” stops being a fantasy and becomes a requirement.

Max Tegmark is an MIT physicist and president of the Future of Life Institute.

We cover:
- Why Yann LeCun’s case against AI safety just got weaker
- The bioweapon question AI optimists keep waving away
- Why so many people believe machines can never outthink us
- Whether intelligence cares if it runs on carbon or silicon.

You can only kill so many people with a rock and a stick.
