Wow Taskmaster You have touched on a very important topic to me.. I strongly believe in the fact that there's a positive side to machines replacing jobs.
You nailed the topic: meaning and purpose in life...
The more time we have in our hands which is not for daily bread, the more our minds get closer to thinking about the true purpose of life...
Here's my description of the purpose of life: Life is an opportunity or chance to experience the universe and everything around us... The chance to be alive means you get to be aware of everything... This is a gift we will cherish more when we're not worried about daily bread. I hope that there's actually systems set to make sure our basic logistics is catered for when machines replace human jobs
