The Silicon Curtain Is Closing. Welcome to the Post-AI World: (Nexus, Yuval Noah Harari)

There’s no going back.
Whatever this book has taught us, there was a pre-AI world and there is a post-AI world. And however it plays out, nothing will ever be the same.

In the final chapter of Nexus, Yuval Noah Harari lays out the cold new reality: AI isn’t building one future — it’s fracturing the world into competing digital empires. Separate hardware. Separate software. Separate truths.

Mark and Jeremy break it all down. The tipping points, the digital arms race, and what it means when the machines stop speaking the same language.

Inside this episode:

• What “The Silicon Curtain” really means and how it's already here

• How data colonialism is shaping AI ecosystems with zero consent

• The mind-body problem in the age of avatars and deepfakes

• What happens when digital personas feel more real than real people

• Why the next great power struggles will be waged through code, not missiles

• And how to build wiser networks in a world pulling itself apart

This is not a story about AGI. It’s a story about power, perception, and the quiet end of global consensus.

One system won’t win. They’ll just stop cooperating.

Welcome to the post-AI world. Try to stay human.

Please enjoy the show.

And don't have nightmares.
