In a few areas we have recognized this need for the surplus capacity, expecting systems to be down some of the time. In this case, society recognizes that efficiency and ability does decline beyond a certain point. This type of thinking can now be applied throughout more and more of society. People need the opportunity to be in peak form rather than be measured simply by the number of hours they work. Continuing toil and overload makes little sense when computers, and machines controlled by them, can take over more and more repetitive activity.
People can move back to more comfortable rhythms.
And there is lots of evidence that they want to do so.
