We all assume the brain is private. What you think, what you feel, what you almost said but didn't — that has always been yours alone.

That is starting to change.

Jörn Rickert, neuroscientist and co-founder of CoreTec and Neudio, has spent his career building devices that go inside the human skull — and music that rewires it from the outside. In this conversation, he breaks down how brain-computer interface technology is moving from paralysis clinics to your Spotify playlist, why your browsing history already reveals more about you than any brain scan, and what happens when neuroscience and sound become the same thing.

Stay curious. Question everything. And maybe just maybe — the most private place you have is still yours.
