Well, to me, it’s pretty clear that the same “perfect” existence could never fully satisfy more than one person. Most of the times, satisfaction seems to come from the fullfilment of some sort of subjective preference, therefore, I don’t think it’s possible for us to create an equally “perfect” future for everyone.
Sure we could put everyone inside their own VR simulation where they would live their perfect “existence”, but many people, like me for exemple 
, would not be satisfied with that because they tend to value some concept of “reality”.
In my opinion, the best future we can get is one in which we all live in what we (in this forum) call a Fractal Society, which is a world where all citizins are free to create their own societal niches in which they can live the way they want, while surrounded mostly by likeminded people.
So, what is the perfect future, you ask? It’s the future in which you can do whatever you want with little or no limitation and you have total freedom and infinite time to explore any possibility that you want and decide what makes you happy.
Ahahahahaha 
I instantly recognized them all except for “Quantum archeology” ( wtf is that 
??!) 
I guess that after sometime in this forum this kind of words just becomes normal.
