The balance between having the fair share of wealth distribution and keeping the incentive on for people to create more ‘machines’ to automate wealth creation. Previously, we are experiencing the failure of socialism due to the labor output was by human being, but now the situation has changed where machines become the output source. Will we need to have restriction on ownership of the machines? Rather than perpetually owning one, the ownership stake shall decay and finally owned by the people through distribution with blockchain (automate)? A very interesting economic problem to really give a deep thought.
