  It's also very empowering for people whose job isn't to run things, but to build the things that are to run. I've worked on a dozen-or-so of bespoke "industry standard" setups, and each and every one had a number of weird quirks, involved learning some new "industry standard" components and either made it very hard and dangerous for non-ops/devops/infra people to run their things themselves, or had homegrown tooling that pretty much replicated what the k8s API can do, just only a small subset and badly. Some YAML and kubectl are well within what a typical data scientist can be expected to understand, more so if it means they can run their things on a dev cluster themselves, and in a pinch, that data scientist can debug prod issues of their things, because it all works the same way. We have a very useful bot that was built and deployed by someone decidedly not ops while waiting for jobs to finish – a simple K8S deploymend YAML is like 50 LOC, with 40 being pretty much standard, et voilà, running bot, without having to build lots and lots of automation in-house or having to take up ops time to deploy this for them or having to grok advanced sysadmin-ing first. Used with appropriate caution and safeguards, it's super powerful.
