I've heard the talking point regarding innovation for awhile now. To me it sounds a bit like an alcoholic with a failing liver hoping that medicine will come up with some miracle cure so they can keep drinking as much as they want.
I think it's the opposite. The push for politics to do something is having an impact, we are making progress in lowering emissions. But it's not enough, and there are constraints on democratically elected leaders. Eventually, public sentiment will change, but not soon enough.
