Art and relationships (including family and friendships) are the two big places left for fulfillment, that I see. Culture and/or institutions (town governments, media, companies, etc) would have to actively encourage people to do active, constructive things, though, I think - the failure mode where you do nothing but watch TV and play video games all day is probably even easier to fall into in a society where material comfort is easy to get and leaving the house is usually unnecessary. Rewarding people with recognition when they do things that are good for them seems like one way - frequent local contests for things like art, music and cooking so people can get social fulfillment from hobbies more easily.
Which isn't to say it won't be a problem - just that there's stuff people can do about it.
I could see religion/spirituality also being a major driver. I could also see an cottage industry of human-made items cropping up as a source of revenue and also of purpose. I guess the big threat is corporations who use this, how we will make sure that things are cheap enough for people to actually afford to do anything?
I finally got into Ello (I was mad that I couldn't get an invitation for the longest time). I found this interesting video about automation and what we should do when most jobs no longer require humans. I have often wondered what we were going to do with the millions of unemployed people when machines create untold abundance. What will we need human workers to do? I have thought that there will be certain areas where we will want to interact with people. I think bots and other machines will be more assistants rather than fully taking over tasks in a few areas. I think it will be more balanced but that does not solve the problem of millions of unemployed undermining the economy and the wealth of nations. Do we save the jobs? Do we stop automation? Is this the natural course of history? Should we all be prepared to be destitute? Should we consider minimum income proposals more closely?

I found it on this interesting post. He projects a much more dystopian view of the Singularity and how it will affect humanity. I think his post is not mindful of Bostrom's work which I am plowing through but it might provide some discussion fodder.
