A measure of the optimism in this community about advances in space technologies. Will space travel advance sufficiently in your lifespan (~100 yrs), that you will be able to afford a trip to space (if you wanted to)?
As much as I would like it to be true, I think my generation will be like Moses who, after leading his people for 40 years, died within sight of the Promised Land. We know the wonders that lay ahead and we are working toward that future; however, by the time we have a public spaceline, people born in the 90s will be dead or too old to benefit from it.<p>However, I deeply believe that we are going to conquer space travel in this as well as other solar Systems.
