I think even it can be better than now BigTex, because we will stop dreaming and get serious. The current mainstream ideas will be slowly eroding, because more and more people don't buy the stuff, and start to see themselves as a part of Nature, not against it. Rising awareness of new ideas will create new solutions.
However the economic outlook of the "praising GDP" society is not going to be great, but human ingenuity is hard to measure, and we will find the way to live great life without so much stuff, we can get there, and fulfill our lives with love, empathy, sensitivity and security. It really counts.
I think it will be the end of a nightmare of consumptionist society in the most degenerated schopenauerian style - that because the life is miserable we need to have more... and more, and more... to kill the pain of our pointless existence. When we can't conform our lives in human-human relations, we live through and by things we control or own, and usually we treat humans like they are things to control and own. This rots society from the beginning, leads to great apathy, unleashes our talents in wrong direction.
For me decline in the pruduction of oil isn't a single-issue problem. It's the way how we budget the planetary resources and how we live on a planet which is an almost perfect closed system. Once we acknowledge this a global society we will understand that we share the same fate wherever we live, and what is more important, we aren't invulnerable as we all thought. We should seek chance to success

The better world is always possible, it doesn't depend on our current style of consumption.
It may be naive, but there is a part of me which hopes it may happen.
The second, pessimistic side says: people die, they don't change; we are aware but resistless; long-term strategy is short-term profit; business as usual; we won't stop plundering, we haven't tried this yet, so the crash is more or less inevitable; resource wars, human greed; deforestation, soil erosion, decline of drinking water; destruction of oceans; rapid climate change when we will unleash the huge reserves of coal; destruction of habitats; starvation; corruption; politics as usual until new Stalin/Hitler alike comes into game; short-sighted behaviour; egotism; infantile narcissism - simple effects of irresposiblity.
What strategy will we choose is still uncertain, and time is inexorably running out.
