I have to agree with death dealer. Besides, there are many problem with this. For one, it takes millions of dollars just to get a rocket into space. Then you would need about 1 or 200 of them. Then for some AI chips you would need a couple more million dollars. Then, the robot thing is impossible. The only robot we could have is one that goes on treads. This would require floating in space, and in space you are constantly moving, so you can't stay and build a ring. For all the metal, thats a few more billion dollars. On mars, we had a 7 min. delay from the time when the robot moved, to the time when you could actually see what it was doing. Then the robot has to move at an EXTREMLY slow speed, since if you move to fast, with the time delay the robot would hit something and blow up, causeing a chain reaction. Then you would probably need people in a space station to moniter things, and fix anything that breaks. That would be BILLIONS upon billions or dollars, then you have to find people dumb enough to do it. Sure living in space seems cool, but look at the dangers. If one tank blows, you all die. One hole in a wall, you all die. And many more. Then you would need a few more space suttles to go up there and refuel the space station, while still making it back on it's own. Then, without a current atmosphere, the plants would die because they don't live on oxygen, they live on what humans breath out. And if you put a pre-programmed atmosphere in a glass dome, whenever you took it off, all the plants would die. Then to get people to live there, they would EACH have to pay millions, because it is expensive to fly there. Then to build casinos? That would require 24/7 attaintion, just like hotels(which I'll get to in a min.) and people would also need jobs, which means it is n garden of eden. And where there's a casino, theres cheaters, people who gamble and lose their money and then the streets would be filled with homeless people. Then when it gets overpopulated, others wil still want to join, but they can't. This would cause riots, sabatoge, and other bad things. To run a good hotel, you would need a pool, game room etc. No right minded person would waste water on enjoyment. You need it to live. The game room would take lots of electricity, meaning that that's less for the ring. Then to keep a stable atmoshpere, you would need constant survaliance, therefore you would be giving people the option to end your lives. Then, if you want people to live there, why need hotels? Not even Bill Gates would pay $10 million or so, just to get up there, then an extra thousand dollars for a hotel room, just to stay for a week. I could come up with so many more, butI have run out of time. This has been a very entertaining 10 min. Bye.
