> People don't need infinite energy to live Our current rate of energy consumption is unsustainable. This is a problem no matter how you want to live (unless you want the entire civilization to go primitive). This is a problem. > This whole line of thinking is short sighted. That's a strange assertion. It's a really long term solution, like billions of years long. As for your magic materials, I hate this kind of argument. It's really just hand-waving "we don't know what we don't know". But we do know physics and we know we need energy. That energy has to come from somewhere. We can't just make it up from nothing. So far the only viable long-term energy options we have are solar power and nuclear power (particularly fusion). There are some far future options like antimatter and using black holes but these don't actually solve the energy problem. They just make really great batteries (eg to have antimatter you have to make it and that takes energy).
