My outlook is significantly more cheery, I must say
Look, if we made it this far, then we're not about to blow it now. I believe that public consciousness is a major part of humanity's survival, and it has never been as "good" as it is now. People, even ordinary, normal people, have common sense, compared to which all of humanity's greatest philosophers pale in comparison. As I mentioned, some of our brightest minds have been predicting doom for year now, and yet the radical and positive movement which they prescribed as the only way to avoid catastrophe has not happened. No one flipped a switch and all of a sudden humanity did an about face. No, the reason we have endured, and will endure is, in my humble opinion, common sense and a self-preservation instinct.
Orwell predicted that World War 2 would end either in faschism or totalitarianism if non-faschist Europe (France, Britain etc) and the US did not whole-heartedly embrace social democracy, and yet neither happened. The West came out of the war more liberal-minded than ever, most major colonies declared independence shortly after and even in the USSR, the hot-bed of totalitarianism, Big Brother was not able to hold on to power indefinitely.
If we leave the governance of the world to nothing more than common sense, which appears to be increasingly and irreversibly the case, we'll be just fine.
