Interesting article on The Economist titled Automation on Automation Angst, http://www.economist.com/node/21661017, that looks at several publications that look at the historical effects of automation, and although there is always fear of being replaced, ultimately more jobs are created than destroyed. Software engineers disappear? So what! There will be other jobs, with different titles, and in the interim, the more people use tech, the more there will be a need for software engineers.
