Of course humans will adapt, the core issue is how we can avoid as much suffering as possible while these changes happen, that's always the point. No one wants to live a life during a transitional period in history where suffering is increased, as a species we should be working to alleviate that.

What's the point of progress if we keep repeating the same mistakes of leaving miserable people behind? Is that progress or just a repetition of the cycle with new shiny things?
