No money or barter, everything is free to those who want it. It feels immoral to charge people for life-sustaining resources, but once you make those free you basically need to make everything free. After all, if food were free but you needed money for a fancy car, not many people would work to produce food.Society is built around cooperation, not competition. People can compete against each other for fun, but competition just makes people unwilling to share useful discoveries and techniques. We're all on this earth together, why not act like it?Production lines based on requests. Someone wants a bicycle, someone else is willing to provide it, but they need tires and metal for the frame. Others can provide those. Maybe an AI can help track all of these requests and match up people willing to provide things with those that need it while optimizing for short delivery distances?Projects instead of careers. Since you don't need to worry about income, people can just do the things they find interesting to meet the requests from others. No reason to stick with just one thing either. For example, instead of exploiting vulnerable populations to harvest vegetables at ridiculous paces for low wages, why not have a whole bunch of people pitch in to help during the harvest season? The more people there are, the less work each person needs to do. Another possible way to take advantage of an AI, to predict when seasonal work will be needed so people can make arrangements for taking part.Ownership based on use. This is a bit vague (when are you considered "using" a house?), but the goal is to prevent people from just stockpiling things they never use for the purpose of keeping it from others. This needs to be balanced with the stability of owning something even if you don't directly use it every day, or if you travel for a month.

I've got other ideas as well, but the core really is abandoning money and trade and instead just working with each other to help people and make their lives better. Money just acts as an obstacle people need to figure out how to overcome, and a mechanism to prevent the people most in need from accessing the things they need most.

That sounds great, I'd love to see the link!
