Shale oil and tar sands are a joke. Maximum production will only ever be a drop relative to super-giant field output. You get poor energy returns due to enormous inputs of natural gas and fresh water and the intensive refining requirements. The ecological horror of these extraction methods alone means they will never scale. The impending scarcity of natural gas will nip shale/tar in the bud right quick, anyway. In about three different ways in your post you said "Don't worry, somebody will figure out a way to deal with these big problems sooner or later." Do you realize that is a very childish mentality? Adults prepare for the future with the means at their disposal.
