I don't get this question. Automation is the job.

We (mostly) don't code in assembly anymore because there are compilers. Your can say that writing high level code (merely "configuring things" in your parlance) is more "boring" than say, register hacks, but that's a bit shallow. (Also, something something leaky abstractions making the whole "it'll only be configuring things!" kind of a moot point.)

Consider programmers from the 80s/90s or early 00s. The ones that still have jobs today are the ones that have kept up with trends and adapted, or otherwise had the luck of being at a place that hasn't. It's the same for the future. Stagnate on old tech, have your career die on the old tech.
