Maybe it is just one personality type but I believe "skills" and what you do or figure out yourself is at the core of happiness and self esteem.
- The food you grow, fish, hunt and then cook taste better
- You feel happier in the house you built or refurbished
- The objects you found feel more valuables
- The music you play make you happy
- The programs you wrote work better for you
etc.
This is just how we evolved and survived until now.
This is probably why an AI / UBI society would probably make worse the problems found in industrialised / advanced economies.
I disagree with the take on UBI. With UBI more people can then pursue a career that is fulfilling for them. Rather than choices of shit jobs to make ends meet.
I imagine one'd have much more time to create things that matter to them as well, or at least the option to pursue such things. Kind of an odd potshot on op's part.
