Sounds exactly right. By the way, are you interested in buying a horse whip factory? When extrapolating future high technology endeavors it doesn't make sense to try to calculate cost/benefit scenarios with today's technology. Although it's possible that our technological abilities will remain static it's a low probability given the constant advancements made in technology. Why send humans into space? 1. To learn how to live in space 2. To ensure the survival of our species 3. Because it's nice to have some other purpose in life then eating, sleeping and excreting 4. Because I don't want to be wearing metaphorical donkey ears as a large asteroid or comet impacts our planet
