We have no other choice probably. But I have no idea what the point of saying it's going to be easy when nothing even remotely close has happened in the history of humanity, and we can't even deal with infrastructure problems for a few thousand people at a time due to the incredible greed inherent to human society. It is rather a humanity breaking event that approaches, and its weight is heartbreaking.
