I concur. Also in feudal times people lived 30 years on average and had horrible quality of life, spending most of the time with back breaking work. Death was common before, during and after birth. We just like to romanticize it. I like fantasy too, but that does hardly reflect history. We as a spices have one advantage that have brought us where we are: the advent of tool usage. And that will be the solution too. On a time frame of 100-200 years we will solve energy scarcity through various means (fusion, focused space solar arrays, rentables, etc.). Then we can build the tools to maintain our current and future lifestyle. We can produce synthetic meat / plant meat. We can start stacked farming with in-door illumination. We can capture methane in in-door stables with advanced air management techniques. We can create terraforming towers mega-structures that remove all the carbon dioxide we blew into the atmosphere and put it back into the ground or into hydrocarbon fuel tanks or something. We are really good at these kind of things, but only once it starts to really hurt. So far it doesn't. There is the specter of hurt to come and a few early warning signs, but in aggregate we don't give a damn about it so far. When we start to burn, our plains become barren and our population is collapsing, then we will start address the actual problems and do something about them. Maybe, the optimistic version. We have the potential to do it. Alternatively we can just bitch about it until the population is decimated and then have the remaining few survivors start a new civilization a few hundred years down the line. Or we just annihilate ourselves because of pent up aggression about the miserable state of affair we brought ourself into. We can be very vengeful if we are cornered. Whatever it will be, it probably will be interesting (for an outside observer).
