did u notice how fast they came up with a vaccine bc the govt invested heavily in it? like moderna was 100% govt last i checked.What old technologies? Name all the things that depend on petroleum for their production then tell us the new technologies that will produce those products without petroleum. You can't because there aren't any. You can't even produce food in sufficient amounts to feed us without petroleum.
wwII - govt put its mind to transforming the economy into a war economy.
we dont need these 100 year old technologies, its only because we let them perpetuate themselves is why we are still on it. we are already a bit screwed by continuing to use them, and will be much more so long longer we drag it out.
