Edit: Changed title to be more accurate.
Also here is the summary from Wikipedia on what Post-scarcity means:
Post-scarcity is a theoretical economic situation in which most goods can be produced in great abundance with minimal human labor needed, so that they become available to all very cheaply or even freely. Post-scarcity does not mean that scarcity has been eliminated for all goods and services but that all people can easily have their basic survival needs met along with some significant proportion of their desires for goods and services. Writers on the topic often emphasize that some commodities will remain scarce in a post-scarcity society.
it’s not just inventors, there are so many other people. Even if food is free who is going to keep or ship it to someone who needs it? and how do you reward them?
I feel like most of the comments here are written by people who have never worked full time job and don’t know how hard it is. Most likely bunch of kids.
