As a SRE, or what I'm going to term "Operations Automation Engineer" (because like DevOps or Systems Administrator, there's a treadmill of terminology), I have often automated myself out of my secondary responsibilities, the ones that take up the majority of my time. At Google, we liked to joke that "It's SRE's job to automate ourselves out of our jobs every 18 months", and I think that from the perspective of time, that was very true. Whatever we spent most of our time on eighteen months ago should be a trivial task today. What I can't automate myself out of is my primary responsibility; Making sure that the site or service is up and available and making our customers happy. I can make constant improvements to that, with occasional backslides, but what I'm paid to do and feel comfortable with my job security is to make a reliable, trustworthy service. That's not going anywhere.
