McCarthy investigates the energy needs of the human civilization in the next hundreds and thousands of years (sometimes going up to millions of years) under the tacit conservative assumption that the basic structure of the civilization and its needs will remain largely the same, only increasing in quantity. Someone who is convinced that, for example, the humanity is bound to go through a singularity event in the next 100-300 years may find much of his reasoning irrelevant.
