Mobile internet, ecommerce, cloud computing and internet of things can make a lot of people rich and help grow the world economy but the impact on our lives would pale compared to aging reversal, regeneration, surgical nanorobots and massively improved gene therapy.
One of the many George Church companies is Rejuvenate Bio. This is a stealth company that has been running tests to reverse aging in dogs.
They are performing aging reversal trials on dog this year and next year. Human trials would be in 2019-2022 and about 2025 before they are done.
They have a pipeline of more than 60 different gene therapies, which they tested on old mice, alone and in combinations. The Harvard group now plans to publish a scientific report on a technique that extends rodents' lives by modifying two genes to act on four major diseases of aging: heart and kidney failure, obesity, and diabetes.
