Perhaps but I'm willing to bet for the majority of those living in rich/developed countries it'll initially just be a slight (but noticeable) drop in living standards - we'll find ways of pushing the costs of our current lifestyles on to future generations (and to those in less-developed parts of the world) for a while yet. And it's not actually impossible that the right sort of technological innovations will end up cancelling out most of those costs - but at some point even the cost of those innovations may well be more than we're able/willing to pay.
