«Ad Altos Labs Vogliamo Creare Una Nuova Medicina». Simone Bianco E L’Avventura Nella Venture Californiana

«Per uno scienziato Elon Musk ha senz’altro meno appeal di un Premio Nobel». Se poi i Nobel sono quattro, tutti seduti nel board of directors della startup per cui lavori, potremmo dire non esserci partita. Tra questi, ad esempio, Jennifer Doudna, che ha vinto grazie al lavoro sull’editing genetico Crispr nel 2020. Simone Bianco, employee numero 27 di Altos Labs con sede a San Francisco, è Principal Investigator e Director of Computational Biology in quella che lui preferisce definire una venture, non una startup. Nel corso dell’intervista gli abbiamo chiesto di Musk e dei suoi piani per salvare l’umanità, anche con Neuralink, ma la discussione ha rapidamente virato verso altre figure, più specializzate nella materia in questione.

Finding The Fountain Of Youth: Meet The Startups Pioneering Longevity Solutions

If technology allowed humanity to live forever in the future, would you take the ticket? We asked our readers recently and were surprised to see the balance tilt towards “No” (60% of respondents). One answer was hidden in a comment from one of our readers – they would want to live forever, yet only if they stayed young. Among others, living long worries people as it is associated with getting old and suffering from various diseases.Yet if technology allows us to extend our life spans it will also likely improve our health spans. According to demographers, children today have a better chance of living up to 100 years old than ever before. But their lives won’t be just longer, they will also benefit from day-to-day technological advances aimed at improving their well-being, preventing diseases, and keeping their minds and bodies in shape.Slowing aging presents an economic opportunity, too. In the US, an estimate shows that just one to two years increase in life expectancy are worth between $7 trillion and $38 trillion
