Actually most devs should have a much easier time with borg than k8s bc there’s an army of sres/devs running it for them. I was one of those running it but even I didn’t appreciate the complexity of running airtight kubernetes distro at the beginning. That’s on onprem tho, if you don’t know how to network just use the cloud thing
I'm not sure what you mean by operationally broken. While I would agree that k8s is not a great match for many, I wouldn't say it's fundamentally broken. It still has many rough edges.
What's amazing about borg is the number of clusters, their sizes, and the support teams that keep them healthy. k8s does not have that.
