Without desire, without need, how can a human live to fulfillment?
Humanity's culture could change, people will do things because they want to rather than need to.
Education can foster curiosity and exploration or innovation of new frontiers.
The primary needs that humans will be feeling might be the fulfilment of interest and entertainment.
Conflict will exist but will major one will be experienced in fiction and make-believe.
Authors, filmmakers, and games designers as an industry will boom but will focus on the creation of new experiences
Apprecations, frame, and prestige will still exist but will start to be linked to the joy you bring to other people.
Many will move to philosophy or religion to fulfil their spiritual needs.
A communal sense of responsibility will develop since everyone will still need to know the basics of history and technology, so to maintain the super high-tech stuff.
That is one possibility.
