"Once we have solved the more pressing problems of the present, then maybe, we will have earned the right to immortality..."
No... That is an argument against going to space, focusing on new technology, etc. the truth is, it can ALWYAS be an argument, the "problems of the present" will either not be solved or new problems will pop up. Europe could have focused on present problems isntead of colonize other areas of the world.
don't use the "lets solve current problems first"
we can work on 2 things at the same time... no reason not to
"earned the right to immortality" if we have the capability to "solve" the pressing problems of the present, we'd have more capability if we had more wisdom, experience, knowledge, understanding, gained by long lives (with technology to keep us young)
