Imagine a world where sharing your thoughts is as easy as sending a text — only now, no typing or speaking is needed. Brain-computer interfaces (BCIs) are making brain-to-brain communication a possible future, where thoughts, feelings, and memories could be transmitted directly between minds, creating a new kind of social media — a “brain internet.”

This technology promises incredible benefits: instant connection, deeper empathy, and revolutionary ways to collaborate. But it also raises privacy nightmares. If your thoughts can be shared or hacked, where does mental privacy begin and end? The potential for misuse by governments or corporations is staggering.

We are on the edge of a paradigm shift, where communication moves from external devices into the neural realm. Society will need to rethink consent, mental security, and even what it means to be an individual in a hyper-connected world.
