No. I'm saying, there is a reason those things haven't' become reality. They have much greater hidden cost than presented. It is the eqivalent of someone dressing in 20th century robe of Edisson and crying over the cruel fate that fell on DC. Much like DC these ideas might see a comeback but only because the context has changed. Not being aware of history is one blunder but failing to see why those thing weren't realized is another blunder.
