Computers in Heaven - Will There Be Bugs?

In medieval times, there were three orders of society: those who fought, those who prayed, and those who worked. Do we kind of follow the same even in a classless society, quote unquote? We still have classes. What I think will shrink mightily is employment in non-service industries. And I think that we really are facing a moment in which we're not quite sure what to do with all these folks that used to be in manufacturing but now have no meaningful opportunities for employment.
