It will be disaster if there are no tangible alternatives to a system of work and it phases out.

Assuming governments and corporations are the likely organisation and foundation builders in this, what do you think will happen? :D

An alternate path and the one I prefer is where work is largely no longer required and essentially, we can do what we want as humans come to understand that freedom and flourishing could be our natural state of existence. I count the chances of this happening fairly slim in the first rounds. Like here, most of the problems would exist if distribution was better but, greed is also a human trait and the enlightenment position of just enough is blockaded by the a scarcity mindset and fear of loss of whatever one is attached to.
