Most places I've worked, <50% of devs could do ops. They dont know systems. We give them some exposure & some pick it up slowly over time. Unlike learning, say, React, most systems are pretty different. Everywhere I've gone has had very different CI/CD & different platforms for running our workload. There's a ton of fundamentals about computing & containers & building (compiling, bundling, packaging) software underneath, but usually the tools are working at higher level & those fundamentals are sparsely seen/encountered, so while a dev might start to skill up in the local ci/cd/platform, the experience only crudely translates l, they have to start way way back, if they go work somewhere else. And then there's the question of architecting. Knowing all the varuous bits & pieces. Our apps use sql, redis, elasticsearch, an object store, an esb... good luck being able to effectively understand & operate all these machines, newly minted senior sev. Coding is way more insular.
