Mind-reading brain chip 74% accurate, hope or nightmare

Stanford announced a brain chip that can translate thoughts into text with up to 74% accuracy, opening up hope for communication for the disabled but raising privacy concerns.

Stanford scientists have just announced research on a brain chip that can decode thoughts into text with up to 74% accuracy.

The chip implants microelectrodes into the motor brain region and records signals as participants attempt to speak or simply imagine speaking.

In particular, the system also integrates a password mechanism, only activating thought translation when the user thinks of the secret phrase.

In testing, the correct password recognition rate reached 99%, ensuring that the chip does not operate unintentionally.

This achievement opens up hope to help millions of disabled people regain their ability to communicate naturally.

However, experts warn that this technology could become a "mind-reading" tool if not tightly managed.

The big question is who will control brain data and where will the line lie between medicine and human surveillance.

Even Stanford researchers acknowledge the need for legal frameworks and technical barriers to protect human privacy.
