I think that humans are in a way beasts of burden and will want something to do with their time that makes their life meaningful. A lot of one's identity is tied to the nature of what they do; literally to the point that a person usually takes their name from their trade. This phenomenon appears to be true regardless of culture, and with automation significantly affecting the human condition, one cannot help but wonder how would people cope on such a time where the individual contribution is not "needed". Sure there are those who would seek to "actualize" and try to live out their existence meaningfully, but it is also true that it is in a person's nature to make meaningful work, a way to express themselves fully through the impact of their actions; and this should not be taken away, through automation or not.
