The potential is mind boggling for sure and one of the most significant change to human development. If this comes to be, it will be enormously disruptive to some of the world's biggest companies, from oil, gas and coal but also to mining and processing, and the alternative energy sector including EV development. And it would be an enormous opportunity for the nuclear energy sector with its waste and the diamond producing sector.
Of course one may wonder how safety would be managed between idiots trying to demonstrate that diamonds aren't unbreakable, terrorists mining batteries or simply how to dispose of outdated products with live batteries...
