I guess we have to get to that future first :) I think we will find the market dictating value a whole lot more accurately... things that are important and basic needs will be the least valuable (this might include electricity, shelter, water, basic foods, health care....) and things that are more "wants" will be more valuable (appliances, specialized robots, art, certain tools...) who knows really...but my guess would be the electricity, compute, information/data will be among the least expensive at that point....
