Well, the first step will be small communities with their own, non-polluting, continuous energy systems.
on the money thing, we will shift to crypto (so no more money printing) and then we will shift to a person backed money, where people have worth, the currency is measure in.
then it is… something to do with inter-small-community settlement layer thingy.
And after a bit more, people will feel they really do not need the money (after everyone learns to give and get)
Why do We need money (in any form, including electronic bits) if We have free energy, and why do We have to wait for "communities" to build up?
It's not a matter of "giving" and "getting." We have 80% and more of Us doing jobs that just push money around. With free energy and automation of needed work no One wants to do (non-creative), the creative needed work will have plenty of Us willing to do it for the thanks, appreciation, renown, and such that They get.
And the money jobs will vanish while everything is freely available, provided by automation and Ones who are doing what They love to do that helps the most.
