Zomato CEO's Brain Device: Science or Sci-Fi?

Zomato CEO Deepinder Goyal has unveiled the Temple device, an experimental wearable aimed at continuously monitoring cerebral blood flow. This open-source innovation, backed by a personal investment of approximately $25 million, is positioned near the temple to capture real-time circulation data. Goyal proposes that gravitational forces contribute to cognitive decline by impairing brain circulation, a concept he terms the 'Gravity Aging Hypothesis.'

Medical professionals, however, express significant skepticism. Dr. Suvrankar Datta, a radiologist at AIIMS Delhi, has publicly labeled the Temple device a "fancy toy for billionaires" with "zero scientific standing." He cautions consumers against investing in unproven technology, emphasizing that measurements from temporal arteries do not align with established medical diagnostics like carotid-femoral pulse wave velocity, which reliably predicts cardiovascular mortality.

The scientific community awaits peer-reviewed studies to validate the device's claims, which currently lack comparison with established methods like Doppler ultrasound or MRI. Potential applications range from cognition tracking for professionals and athletes to monitoring the elderly, but its true role as a cognition-tracking technology will only become clear through further clinical trials and proven safety.
