These are deep, important questions. I wonder how people will go about fixing the problems of food sustenance and wildfires in the years to come. Will we innovate incrementally or through big ideas?
When I was reading through your points, my mind popped up with the industries built in the 19th century. For instance, the steel business industry innovated itself to be inexpensive (e.g., via Bessemer Process), to generate not only jobs but also interesting economies. Though, there are also positive and negative externalities to think about with all this stuff.
I totally agree, pushing the envelope with real ideas is key.
