There’s reasons Mother Nature picked evolutionary change, not revolutionary change. Revolutionary change is much less successful. When something goes wrong and for whatever reason part of our growth process thinks it knows better but doesn’t and sadly turns into cancer. Incremental experimentation results in minimal loss in case things go wrong. No one would ever do this right? Wrong! Ban our main energy sources, make it too expensive, rip out that infrastructure. The sun and wind will keep us warm! Energy density says no, Einsteins. I’m ready to shovel that global warming Monday. Let it snow!
