Future tech or fancy toy for millionaires?

A podcast conversation around Deepinder Goyal sparked debate over an experimental metallic head wearable designed to track brain blood flow.

The device is part of a $25 million private research project and is not a consumer product.

Doctors and experts question its claims, citing a lack of clinical proof and peer-reviewed research.

With no regulatory approval and mixed reactions online, the big question remains whether this is a glimpse of future technology or just high-priced hype.
