But then it morphed into "oh lets innovate with infrastructure" but the innovation turned into "lol lets just restart from scratch and ignore history" Anybody who used early k8s can attest to how un production ready it was for the longest time. It _felt_ like progress because it required a lot of (to dev eyes) hidden magic to make it work.
Now, we are back with sysadmins, but they are called SREs. They provide a platform, which devs talk to to deploy stuff.
Basically we're back where we were in 2015, just with more yaml.
The good things that have come out of devops has been the dashboarding and metrics tools. Its just a shame that everything else touched by it appears to be an infinite source of busy work (looking at you kubernetes)
(before anyone asks, I'm an SRE at a FAANG.)
