We live in a post information scarcity society and we still haven't moved on from capitalism.
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.
Capitalism will collapse eventually, whether planned or not. The best we can do is build up parallel structures that can weather that collapse, like complex networks of Mutual Aid, strong Unions, FOSS software, and more.
The rubes need something to collect so they can lord over you. They don't want an intelligent society. They want something they can game to get big numbers.
The problem is that while we have infinite information we do not have infinite energy/resources yet. The shift when we get it to remove power from the structures will be larger but reminiscent of the piracy/copyright battles lately
Firstly, capitalism isn't going to just "poof" away just because there are more resources available. The rich will just hold them back to create artificial scarcity - like is done with diamonds.
Secondly, even discounting that, there are plenty of resources that are genuinely scarce no matter how much money you have to throw at the problem.
But if you're referring to just the scarcity of information - then you're still not quite right as not all that information out there is good information - a lot of it is misinformation (i.e. propaganda, etc.)...
And even that discounts the fact that for many people, they don't have the tools/capability to access the information, or simply can't access the information full stop (I.e. due to censorship, etc.).
We're in a post information scarcity society and there are still people out there who think the Earth is flat.
Simply providing people with the answers is not enough you actually have to make them believe those answers, and there's always going to be people who are desperate to not accept those answers because doing so would make them the same as everyone else, and of course that's not possible because they are special. And they are special, just not in the way that they want to be.
Capitalism incentivizes production so well that the mere charity of individuals provides more for free than all the redistribution the government can manage under a controlled
economy.
Capitalism’s primary activity is commerce, with a tiny sliver of charity on the side. That tiny sliver of charity is the biggest pool of resources made available for free under any system.
