If it were to prove to be the real McCoy then I'd certainly agree that it would be an amazing and very positive breakthrough that would have enormous benefits given the challenges we face.
My concern is the potential it would have, whilst solving one enormous problem, that of anthropogenic warming, to replace it with a myriad of others.
The pursuit of growth would be enhanced on a still finite planet and the human race would soon face new challenges for survival.
I suppose it would be a good problem to face but would we be able to create a new world order that could manage the opportunities equitably? Would we be able to ensure that Africa would reap the early benefits for example?
