I think we need to take some wise advice and not put all of our eggs in one basket. Cryo is in its infancy, as is space travel, so we have no clue what problems we will face as we try to go to other locations. The question becomes, how quickly can we get both technologies up and running efficiently and safely?
There is also the question of if people should stay on earth or if we should abandon the fragile blue marble to allow it to “go back to nature.”
Personally, I think we as a species will be required to look at every aspect of our lives and work towards getting a good chunk of the population off this rock and leave some to maintain humanities few truly priceless legacies.
I plan on diving deeper into both types of ships as I explore the current tech and the speculative fiction.
