What point does this serve?? Its a guess...and we'll most likely never know if its true or not. Cuz most likely none of them are giong to happen this
year or the next.
The best part regarding guessing about a breakthrough in technology is
that you'd have to predict the technology first. In other words, instead of
saying the space shuttle will be replaced, you would have to suggest what
it would be replaced with.
Foreseeing a new technology is the most difficult part. You would need the
imagination to see a technology that isn't in development yet.
