Yes, the nature of work will change as it has in the past, perhaps more rapidly now than people and families can deal with it. 

What won't be measurable is the loss of virtue that will occur in people, by either not having to work or not being asked/demanded to work.   Work fills out and develops our capacities in hundred different marvelous ways.   

Free choice exercised - perhaps against the complaints of the body and appetites - to serve the good of something outside of us.   That's what work offers us, and why God invented it for us.   On several levels, there will be a regrettable loss.   

Losing the demand of work could be the greatest loss.   I'll simply have my servant robot work for you!
