You do know that the '70s oil embargo really wasn't about oil at all: oil was just a weapon used in a dispute that was (and still is) fundamentally about religious and ethnic differences. (That much is history: further comment would descend into politics, so I'll refrain.)

To the original point, EFI systems are much simpler than carburetors, especially the ones used on automobiles from the mid-50s on. If you've ever taken one apart, you'll have seen that they're a maze of passages filled with jets, valves, springs and such, which all have to be sized right - and clean - to function properly. Then you have to painstakingly adjust things by hand to get mixture & idle speed correct, except that 'correct' only holds for a particular elevation & temperature range. And don't even get me started on trying to balance multiple carbs...

EFI is brilliantly simple by contrast: a simple pump squirts a measured amount of fuel into the cylinder, while a sensor measures the exhaust and uses a feedback loop to correct the amount.
