you just say that because "you don't understand" how things were before. none of the things that you mentioned solve any problems, except to temporary remedie the one's that they created.
the abilty to travel long distances is probably the biggest bane of humanity. on the most basic level what that means is that people didn't build things 15 miles away from each other if they didn't want to walk that far, or they did if they wanted the privacy. on a level of "thinking outside the box" that means that people lived in a small area and didn't move, which created a tight-knit community where everyone knew each other and had relationships and accountabilty and they had to all get along with each other because they didn't have a choice. Yeah, we really had to get the fuck away from that. It also forced people to have to make use with what they had because they couldn't get anything else so they didn't waste or trash or over-populate. There was no need for cars until the invention of the car when everything shifted over to being geared toward car culture, instead of people culture.
In addition to all that, this wonderful invention is one of the most deadly things ever made, not even counting all the pollution that it spawns. In the 1990's more people were killed in car accidents than in every war the US has fought in put together. Is that really worth it, and for what? It hasn't made anyone's life easier or less complicated.
all the same thing can be said about trains, accept that they have a far more fucked up history. alienation, ecological destruction, industrial accidents galore, and add onto that stolen land, bloody violent conflicts and horrible oppression and exploitation of workers.
Now that everything is industrialized and trillions of tons of poison, chemicals, and radiation are floating around causing all sorts of new diseases and cancer rates to go up and up and up we all scuddle about for new medicines to save us from ourselves. yeah, what a brave new world we've made.
The fact that only a very slim majority of the world's population get's to enjoy these "luxuries" at the expense of all the poor people that have to slave and toil and die for them makes it seems like a pretty sick, fucked up waste to me.
