Humans are obsessed with reaching a state of never ending bliss. Religions promise heaven or nirvana and we search for gurus who claim to have achieved enlightenment and try do what they recommend.
A while back I came across this "letter from utopia" written by Nick Bostrom (or his future self). This utopia is not supernatural, it is a result of constant improvements to our condition. We can plausibly find ways of enhancing ourselves cognitively and emotionally. It's also plausible that one day humans will have very long lifespans. If we could do these things consistently over a long period of time we would end up living in a very different state to what we're used to. If the improvements are in a direction we could all agree are good, enough of them will get us to utopia (depending on what we decide qualifies).
I can't see any problem with this reasoning, but nobody I've spoken to has shown much enthusiasm for this potential utopia. Why not? Is it because it seems so soulless?
