While Doomsday is proceeding with cautious optimism, life as we know it in general, has no example of going on endlessly. At least not in this solar system. Is Earth an exception? No. Everything is finite.


Evolution has reached a certain level of efficiency in the chemical transference of energy to another organism via eating and digestion or for stationary flora enhancing the chemical process with solar energy.


What I'm getting at is that the most efficiency we can ever expect from the best possible economic system will probably be no more efficient than Earth's evolved 3 billion year old living systems. The system will have to be synergistic. And as most have pointed out, continual unlimited growth will always be stopped by other factors.


So even an ideal system that destroys/exploits the environment the least is still mortal. Best to just enjoy the ride while it is still here.

That's why Elon Musk wants to blow this pop stand. :^/


or will fusion or 'dimensional dark energy' discoveries change the equation?
