An enjoyable and thoughtful read as we discover, along with the robot, what humans may need.
An enjoyable and thoughtful read about the continuing journeys of a tea monk and a robot who wants to know what humans need. Plot-wise, there isn't much; but in terms of musing over the condition of humans, nature and one robot, there is plenty.
Both the monk and the robot have returned to human civilization, with the robot eager to visit and discover more about the human area and various human communities (with one exception) eager to learn more about the robot.
Through their interactions, the robot (and us readers) learn more about the human society that rose after the robots achieve sentience and left the factories, and about how they now live in a more ecological sustainable manner while maintaining some technology.
But would it be enough to answer the question the robot first asked about what humans need and how it can help them?
