RE: Technology Overcomes Scarcity

My father was an American citizen but he was not American. He was an old-world European. He was always concerned we were going to run out of clean water even though the Earth is 75% water, the oil discussion would cause him to get angry as he truly feared a world without oil.
I also have fears of running out of basic materials. I think you are right as this will only limit us, by indulging in unfounded fears. Recently (last few months) I have been focused less on fear and more on just getting things done.
