I’m biased. I worked in teams with such people basically my whole career.
The pay increased, the titles and tools changed but the mentality didn’t.
People just started beating their chest about devops and pooping on the legacy of sysadmins which is what most devops/SRE are.
Sounds like they were automating though.
“Cattle not pets” was a sysadmin mantra, but the business wanted pets most of the time.
