The short form is that they've solved Friendliness and handed most of the management over to hyperintelligent, near-omnipotent benevolent AIs. The only real problems left for individuals qualify as "how to not get bored", which for the most part they approach by cultivating eye-watering arrays of esoteric and satisfying hobbies, projects, arts and crafts, high-brow debates, luxurious indulgences, social groups, and games. The few people that still aren't satisfied generally end up in their diplomatic corps slash military slash spy agency slash police force. "Ultimate" may have been an exaggeration, but it is by far the most satisfying utopia I've seen described.
