Random thoughts: - One of the biggest problems we have is how to produce and preserve energy in large quantities in environmentally efficient way. If we are able to do that then 1, 2 and 4 are just nothing special. We will be able to tackle on the space! - Wi-fi spots on everything? That is missing the point - I would argue that not the one-time cost is the problem but rather the cost of service associated with it. - Idea 5 is so wrong that we must try in every way to protect from it. I can see the benefit of having the weather always in your sight, but I'm afraid that we as society will deep dive into it and never come out. - War on asteroids? Better war on cockroaches. That is just wasting money on nothing. Now if we are endangered by some concrete asteroid, then we have to shoot it down of course. - And building skyscrapers for me is missing the point. We have enough of these. Better spend money on preserving the environment and species on our planet then trying to squeeze more people on a square meter. Or just build the damn space elevator. I have a dream - my son to take me on a space trip :)
