Aaron, the critical feature of deductive reasoning that is often ignored is that this reasoning is based on a set of assumptions. We must first accept the assumptions and then proceed from there.
In the service of clarifying the situation, I wish you had identified your assumptions but since you haven't done so explicitly, I'd like to make a stab at what they might be:
1) The past is a guide to the future. We can expect the future to be similar to what's happened in the recent past.
2) The history of human civilization is a triumphant march of success upon success.
The problem I have with assumption #2 is that history is written by the winners, and most people's understanding of human history is weak. It's important to recognize that there have been many spectacular failures of powerful civilizations. You should remember that the fall of Rome was succeeded by a millennium of "dark ages". There was a brilliant civilization in the Yucatan that disappeared a long time ago and left only relics and language fragments. If you want to use the past as a guide to the future, you should keep in mind that civilizations generally fail at some point.
The problem with using the past as a guide to the future is that you can pick whichever aspect of the past supports your argument, and ignore the other parts. This is called "cherrypicking".
The people predicting oil depletion and the ensuing economic hardships are engaging in inductive reasoning. This involves taking known things, such as known oil reserves, patterns in oil discovery and consumption, and the laws of thermodynamics, and using this information to project from the present into the future. Some of these people know what they are talking about.
I don't think it's a good idea to trustingly sit around and faithfully hope that "they" (whoever they are) will invent a fix for our current - uh - fix. The best projections for the peak of oil production range from "right now" to ten years from now. As soon as production starts declining, the troubles will expand. Meanwhile, the best guess for a fusion reactor is about 40 years in the future. The Hirsch Report pointed out that developing infrastructure to partially mitigate the loss of oil and replace it with alternatives will take on the order of 10 or 20 years.
Will someone invent a miracle energy source in the next ten years, and find a way to scale it up tremendously in only a few years, in the face of possibly crashing economies and resource wars? Personally, I think it would be much better if we all parked our cars and started using public transportation.

I suggest you read "Collapse, How Societies Choose to Fail or Succeed", by Jared Diamond. There is ample evidence that humanity has not always "innovated" out of an poulation overshoot/resource depletion scenario.
The problem is, of course, that not only is economics bankrupt, but it has always been nothing more than politics in disguise... economics is a form of brain damage.
