An anonymous reader writes: An article at The Guardian takes a look at the way in which we hold jobs as technology as changes. Its central thesis is this: "My father had one job in his life, I've had six in mine, my kids will have six at the same time." This may compress the generational changes a bit, but it's an interesting point; the average time people spend at one job has been trending downward for a long time. As technology enables the so-called "gig economy" (or "sharing economy," if you prefer), we're seeing many more people start to hold multiple jobs, working whichever one happens to give them something to do at a given time. Economist Jeremy Rifkin says, "This sharing economy is reestablishing the commons in a hi-tech landscape. Commons came about when people formed communities by taking the meager resources they had and sharing then to create more value. The method of regulation of these systems is also comparable. If people are trusted and vouched for they are accepted as part of the sharing economy group. If they behave badly they are excluded. Your social capital means everything in this new economy."
