I find it ridiculous to spend billions of dollars to attempt this! Can people of the world really not see a better place to invest??? What will this accomplish? The answer is that nobody knows what it will accomplish. Someone else tried to do this about 10 years ago, spent millions and the thing never worked. And even if it did work, what's the point?
To me, it looks like an extravagant way for some egotistical maniac with a God complex to get attention. I think it needs to be stopped.
