Hey, did you know that the worldwide demand for oil will outpace production in the next 20-40 years? Price goes way up, oil-dependent economies crumble, wars over energy resources explode. The fix? All we need is "a few dozen technological breakthroughs; unprecedented political will and bipartisan cooperation; tremendous international collaboration; massive amounts of investment capital; fundamental reforms to the structure of the international banking system; no interference from the oil-and-gas industries; and about 25-50 years of general peace and prosperity to retrofit the world's $45 trillion dollar per year economy, including its transportation and telecommunications networks, manufacturing base, and agricultural systems to run on these new sources of energy."
Or maybe we'd be fixing the wrong problem.
What will you be doing in 20 years?
