content: I think people think too small now a days. Think about something as ubiquitous as power lines - how insane that must have seemed at the time. You want to string up polls with wires with enough juice flowing through them that a human having the electricity flow through and out them would be instantly fatal - where a tree collapse or other issue could be a major fire hazard and so on. And now you want to string these up, connected to each other, basically everywhere in the the entire country. Making a passenger carrying underpass seem rather banal by contrast! There's so much we could already do today, for instance with solar or even internet, but we've become so averse to huge changes as a people.
