I believe money is the reason (isn't it most of the time?). There is plenty of money to be made from Mars and the moon in the future, may be with mining, or even turism, but it will certainly be made somehow. May not look feasible now, but it will be in a century or two.
goombah99 writes "Dan Rather Reports has posted a lengthy YouTube teaser of their upcoming touchscreen voting expose (to air tuesday at 8 or 11pm ET) This is sort of a "60-minutes" style investigation of touchscreen voting. It's apparently not a rehash either. Rather turns up some new evidence such as tracking down the dilapidated plant where the ES&S ivotronic touchscreens were assembled. There they were having a 30 to 40% rejection rate on the screen themselves. Apparently the issue here was a rush to market to meet the election schedule. They needed lots of machines, fast. So plant workers say the rejects got shipped too. The "rush to market" aspect demonstrates an often overlooked strength of the use of open source software with commodity hardware and a multiple vendor business model like open voting consortium. This should be much less subject to single source point failures and has a built-in adversarial oversight nature that might lend some quality control. I just hope their conclusion is not "we need perfect machines and perfectly trained operators" and instead is we need a different approach that is transparent, robust and self correcting in the face of errors."
