What you’re describing is mostly in the application side of things, though. You still need Ops to run all the infra, which is what most places’ SRE role really is.
Most devs I’ve worked with didn’t have any interest in dealing with infra. I have no problem with that; while I think anyone working with computers should learn at least some basics about them, I completely understand and agree with specialization.
I mean, I'm SRE/Ops but every company I've joined, I've been brought in to manage the infrastructure from ball of wax some dev got operational enough to limp into prod. When I mean limp, they are truly limping and couldn't run to save their life.
You need someone to be disconnected from getting birthday to display on the settings page and make sure Bingo, Papaya, Raccoon and Omega Star are just up and running. Esp since Omega Star can't get their shit together.
I haven't seen an ops team run infra in awhile. They're all software engineers writing abstraction over cloud. Infra is like "platform" now and they are swes running it.
