Scarcity is imposed by physics. Energy is conserved, entropy increases. Even if we realized the wildest extropian dreams and moved all intelligent life into efficient simulations, physics still dictates that every non-reversible computation creates entropy.<p>A homeless person in the US today has universally better prospects than 99% of the population a thousand years ago; better than all of them in many ways. It’s impossible to starve in a first world country. Even the poorest of the poor are jacked into the global communication network. Necessary survival goods are non-scarce. Are we satisfied? No, we want more. As productive capacity increases, our definition of non-scarcity becomes more and more demanding. I don’t see why this would stop if the only commodity left was mass-energy.
