What Comes Next

What If Humans NEVER Needed Sleep? You'd Get 26 Years Back. And Lose All of Them.

Tue, 16 Jun 2026 14:20:46 GMT

You will spend roughly 26 years of your life unconscious. Science still cannot fully explain why. In this episode we trace what the research actually shows about mortality rates, cognitive collapse, and the brain cleaning itself while you sleep. We follow it to the edge of what we know. Then we ask what happens if that changes, and we follow every ripple forward. Where we leave the historical record, we tell you.

Right now, AI systems are holding more conversations than every human being on earth combined.

And nobody can tell you with certainty whether any of those systems feel anything while it happens.

In this episode, we trace what we actually know, follow what happens the moment that question gets answered, and never let you forget where the facts end and the scenario begins. New episodes every Tuesday and Friday.
