The demarcation from this world to the next may not be a singular event that will ever be defined. It may very well be imperceptable on a daily basis and only recognized looking back through decades in the future as external events forced us stubbornly against our will toward a transition.
For this reason you may be creating a false dichotomy between this pre peak oil world and the next post peak oil world. Institutions will reinvent themselves and morph slowly as apposed to collapsing and building themselves up from scratch.
An analogy from biological evolution....An eye was built on imperceptably slow modifications of already existing features and not from a design reinvention. Culture is free from the constraints of genes but not from memes which replicate and mutate also based on pre existing paradigms.
Too many people project collapse based on their personal disdain and hatred of the existing paradigm instead of rational analysis. Remember, these changes for the masses are not driven from idealogical roots but from reality and geology that will put huge strains on existing idealogies of consumption. Changing this will be a slow imperceptable grinding affair the speed of which is somewhat dependent on the rates of decline of fossil fuels but not solely. Changes in lifestyle hold the biggest scalable reserves on energy along with the incrementally slow rise and build out of renewable energy. Disease and global warming throw in unpredicatable variables.
These are all good reasons to pursue your engineering career!
