> It would cost many billions of dollars, the potential rewards are unclear—and the money could be better spent researching threats such as climate change and emerging viruses ...and still there is no viable way to get rid of plastics out of the ocean, on how to treat Nuclear waste that remains active for centuries or how to get rid of the CO2 in the air. Not to speak of Nuclear fusion which would solve at least the CO2 emission side. Physics that was once new actually enables solar power, optical trash sorting with lasers and what not. New Physics could advance quantum computing which in turn could enable better weather simulations. The whole arguments seems pretty short-sighted and anti-scientific to me...
