Sam, I'm reading a book about the Second Machine Age, future trends, past technological advancements, etc. Very fascinating how technological innovation growth, settlement, population, health, etc. are tied together. After the steam engine, digitization (IT) and plumbing, the switch from window unit ACs to central AC systems is one of the biggest drivers of social change in history. I believe we are witnessing it first hand in our lifetimes and our regions' loss of population to the sun belt. It was near impossible to live comfortably in the deep south during summers. Taxes + bad weather are a toxic combination for growth. You can usually survive with one or the other but not both.
