To be clear, I never said technology was the only solution. We have to parallel-path this entire enterprise. We need a change of culture and values just as much as technology. I'm not counting on only technology, but I really do believe we'll need both approaches here. As engineers, our part in this may be to create technological solutions. I hope culture thought leaders do their part and espouse a different way of living that replaces material consumption and status symbols with real human community.
