Nerval's Lobster writes: By some measures, more than 40 percent of U.S. workers will be independent in 2020. Today, that number stands at 34 percent, according to the Freelancer's Union. By all accounts, the trend seems widespread enough to indicate that tech pros should prepare themselves for the dynamics of a world that depends more on contingent work. The question isn't whether the tech world will see an increasing prevalence of 'gigs,' rather than full-time positions; it's whether those in full-time positions can easily keep their jobs when there's pressure to farm it out cheaply and easily to freelancers. Or will the need for people who can see projects through the long term prevent the 'gig economy' from radically changing the tech industry?
