Would contemplation, laughter, love, bliss... count as purpose ?
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.
Work will disappear for most of us. What will we do with our time?
Still, there's differing levels of dystopia. One where humans are still able to help each other is certainly better than most alternatives.
