"What year did the change gas pump?" I don't know the year, but I suspect that the primary driver for the change to gas pump readouts was the advent of cheap electronic displays. The cost of a gear-driven mechanical display is roughly proportionate to the number of digits displayed. Contrast this with electronic displays, in which the processor and supporting infrastructure is the bulk of the cost, with the cost of one additional display digit almost insignificant. If you are going to build a gas pump display with an expected useful life of 10 years, you might as well cater to many possibilities. The fact that this switchover came along at about the same time as self-serve, credit card scanners, and the first and second energy crisis probably helped drive a relatively rapid conversion. "Just who are the people that cause prices to fluctuate with an upward average?" I think it's the 6 billion people on this planet, all competing for a finite, vanishing resource in a world-wide market. With rapidly growing demand in India and China, we have accelerated the point of "peak oil" from maybe the year 2020 to ~2010 (or maybe even today). Once we hit "peak oil" it's all downhill, very, very rapidly. "Who gets the money from $70 per barrel oil?" Mostly, it is the owners of the oil and the folks that pump it. With the price of the raw commodity rising rapidly, there is room to "hide" substantial profit increases for everyone else in the supply chain (hence the record profits for the oil companies), but the most of the money goes to the owner of the oil. "Will gas go up to $3.75 next year?" Almost certainly. The only likely brake on rapid inflation of energy costs would be a massive world-wide economic slowdown. "Looks like we'll all be using Italian motor scooters" Yes, we will. The idea that we can have "developed" and "developing" economies which will all end up with an American lifestyle is fundamentally faulty. Instead, no one will have it. I predict that no large population on earth will have the "Mom's taxi, SUV driving, energy intensive" lifestyle typified by this country in the 1990's within the next 10 years. Since God is not making more dinosaurs, and many people and cultures seem to insist on making more people over and beyond simply replacing themselves, the energy future overall looks pretty bleak. Imagine the squabbling masses all fighting over the last few drops of oil. This will happen within 50 years, unless something worse happens first. If we could figure out effective power production from nuclear fusion before we kill ourselves off from global warming or fighting over the last few drops of oil, humanity might have a chance of surviving beyond 2100. As things stand, I am glad I got to live in the era that I did. The long-term future doesn't look pretty.
