Zomato Founder Defends Temple Device Amid Criticism
Deepinder Goyal, the founder of Zomato, has been wearing a small device called Temple near his eye.
This device is meant to monitor blood flow in the brain, which can tell us about how the brain is working and how we age.
Some doctors and experts have criticized the device, saying it's not scientifically proven and is just a fancy toy for rich people.
Goyal has responded by saying that the device is still being tested and that people should wait until it's officially launched before judging it.
He also explained that he has been working on this device for a year and believes it could be very useful for understanding brain health.
He has even invested his own money to develop it.
Goyal asked people to be curious and supportive of Indian startups instead of being skeptical too soon.
