The 2020s will be transformational for humanity, according to the tech prophet founders of RethinkX,

Tony Seba and James Arbib talk to Justin Rowlatt about their prediction that a confluence of new technologies - in energy, transportation, and food and materials production - could wipe out poverty and solve climate change in the next 10-15 years, and usher in a new "Age of Freedom" for our species.

But while it sounds utopian, they also warn in their new book Rethinking Humanity that it could pose huge civilizational challenges for a planet that still clings to outdated concepts such as democracy, capitalism and the nation state.
