Automation will conquer most of the workforce, especially in the production line. However, i dont think man will lack what to do to raise money. We adapt everyday to the evolving nature of work as a whole. Just like in the now, in the 'then' those who fail to adapt to the new work trends will drop like diseased cattle from poverty.
But, the future will definitely be brighter in terms of poverty reduction. Resources will be shared "almost" equally and the gap between rich and poor will be reduced too.
crypto-currency tech may be very helpful then.
