It's funny, a few years ago I was telling people that the cost of electricity would eventually approach zero, as solar panel efficiency improved, but I honestly think people thought I was mad. Talking about "free energy" still makes people think you must have a screw loose. But if you don't think in capitalist terms, and try to imagine a world where technology and traditional lifestyles in which humans barely worked to survive (hunter gatherers didn't have to work too many hours to hunt and gather enough food to live) can coexist, a better world where we have our needs met and DON'T destroy our environment is actually possible.
