I anticipate a future where we redefine a work-week as the duration of a specific just-in-time gig, a weekend as the gap between gigs, vacations as opportunities presented by anticipation of long gaps but subject to sudden termination when new opportunities occur.  The day itself will have break times that will vary day to day and may arise with no advanced notice, leading us to arrange social encounters with near-strangers who happen to share something in common including the fact that they are free at the same time.
