Why would those be purposes? A single person may want to contemplate, laugh, love, bliss, etc., but it's not a justification for his/her existence. And it would be remarkably egoistic and empty if I want to enjoy a hedonistic lifestyle.
For me, the purpose for humans is to serve other humans, to work. Which we are increasingly unable to do because it turns out that this 'work' can be more easily done by mechanical brutes that happen to be programmed by humans.
Oh, not necessarily egotistic, at all. Sharing and spreading knowledge and wisdom and calmness can be a noble purpose. Helping those in need is one form of true love.
Work will disappear for most of us. What will we do with our time?
I don't know. But I think that if we ever get to that point, then it would probably lead to a doomsday scenario of existential angst. Anything that happens after that...is really a boring footnote in the history of machinery's triumph over humanity.
Still, there's differing levels of dystopia. One where humans are still able to help each other is certainly better than most alternatives.
