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.
Perhaps we live in a post DATA scarcity society. But information is still a scarce commodity
I think that we do live in a society where information is not scarce because the ease of replicating any information has increased significantly.
That does not mean everyone has access to it
The idea in relation to capitalism is referring to information from a physics standpoint, not from a data analysis standpoint, as in Information Theory and it’s laws as opposed to the laws that govern matter / energy.
