I’m not going to argue against green tech– it needs all the energy the economy can muster right now. But I want to caution against technological optimism as the solution for our current ecological crisis. It’s a cultural problem, and I hope that people are not blinded by one-sided change in which tech solutions supplant cultural creativity. Both are necessary, but let’s be sure to reign in the technological mindset that sees all solutions as a matter of switching out machines. We have to move from mechanistic to holistic thinking, from centralized energy production to decentralized network distribution, from international trade to local production, from finance to sweat equity, and so on.
