Why do the world's tech billionaires want to extend their lifespan, their business has reached Rs 54 lakh crore?

In early December, Deepinder Goyal revealed that his latest invention, an experimental wearable called Temple, was coming soon. At first glance, this small golden patch resembles a jellybean, but according to Goyal's own social media posts, he's been wearing it for a year, and it promises to do much more than its minimalist design suggests.

Goyal, CEO of Eternal, the parent company of Zomato and Blinkit, has spent a lot of time exploring food delivery, quick commerce, and new experiments in 2025. Now, he's moving swiftly into deep tech and longevity. 

With Temple, a wearable device designed to track blood flow in the brain in real time, Goyal has become the founder of this latest technology, which believes that aging is just a technical problem waiting to be solved.

Big tech leaders are investing money

He's not alone; the conversation about living beyond 100 has now moved from science fiction to geopolitics, with China's Xi Jinping and Russia's Vladimir Putin seen on a hot mic earlier this year talking about living to 150. 

For more than a decade, tech leaders have been investing in extending human lifespan. Goyal's entry is India's most high-profile addition to this global movement, which until now was dominated by US tech founders.

So many tech entrepreneurs are moving in this direction, but why aren't pharmaceutical giants? Unlike Big Pharma, tech billionaires have a very different view of the world: death is an engineering problem, not fate. 

Peter Thiel, who has supported Unity Biotechnology and the Methuselah Foundation, once told Business Insider (2012): "There are many people who say death is natural... The truth couldn't be further from that."

They built software that reached billions of people; now they're looking at biology, cognition, and aging in the same way: as systems that can be optimized. 

Research on longevity takes decades, and tech founders have both the capital and patience to make long-term bets. Reports suggest that Jeff Bezos is backing Altos Labs, which aims to cure diseases through cellular rejuvenation.

This company of Elon Musk is doing wonders

Much of the excitement is surrounding Neuralink, Elon Musk 's brain-implant startup, which is valued at $9 billion and has sparked a race in this field.

Neuralink is moving not only toward medical but also consumer applications. Bloomberg reported earlier this year that it aims to implant a device in a healthy person by 2030.
