We're not yet in a post scarcity world. We're tantalizing close, but not quite there yet.
There are three main areas we need to work on.
First is power generation. We need more, and it needs to be decupled from fossil fuels. Nuclear is the obvious answer for massive amounts of power output without using massive amounts of land, but fossil fuel lobbies have been hamstringing development since the 50s.
The important thing here isn't just replacing fossil fuels. That would just leave us were we are now. No we need to double or triple world power generation as a start.
The second area that needs work is connected to the first. Transportation. Not just electric cars, but container ships and trains and everything in-between.
This is where that added power generation comes in. We need to make it basically free to move things from point A to point B. There are some ways to do this, particularly for container ships. But we need the raw power available before they become viable.
The final area is automation. We need more. Once people need to be put out of work in massive numbers. We need to decuple work from life.
That final step is the hardest with the most pitfalls. It will happen. Well, the automation and unemployment will happen. After that we can either spiral into a hell scape or rise above into a post scarcity utopia...
It really depends on when and how the guillotines come out
