INSIGHT

Brain Data Completes The Puzzle

Brain data becomes the 'final piece' that, combined with camera and behavioral data, yields precise psychological profiles.
That fusion enables AI to infer feelings and eventually thoughts over time.

ANECDOTE

Workplace EEG Caps In Use Today

SmartCap sells EEG-embedded headbands to enterprises for fatigue detection in workers like train conductors.
Over 5,000 companies require such devices to monitor alertness for safety in high-risk jobs.

INSIGHT

Professor Nita Farahany, author of The Battle for Your Brain, is one of the world’s leading experts on the ethical, legal, and societal implications of emerging technologies and their impact on our brains.

We discuss how every major tech company is racing to build devices that could replace keyboards and smartphones with your neural signals — with AI glasses, smart rings, wristbands, and earbuds as the first step.

Professor Farahany breaks down why the brain is the holy grail for tech companies, what these devices may soon decode, and the massive privacy implications. We get into what brain data can reveal and why “freedom of thought” is suddenly up for debate.
