I think while ressources are available, localized event (even major) and its not world-ending, this is true and a beacon of hope in humanity.

However when ressources are no longer produced, people get hungry and desperate with no lights at the end of the tunnel, i.e. real game-changing global catastrophe, I hope I am wrong (and hope even more to never test that theory), but I doubt this would bring the best of humanity overall.

Fear mongers have one good thing: if you can reply with facts and destroy their theories, nutcase aliens mind controlling aside, it means that it has been studied or acknowledged. Simple dismissal might not be the best way to fix holes or anxious bodies.
