> DevOps as a movement died when it started being used as a job title. In my experience, it quickly stopped being a philosophy for Dev and Ops teams to work on working better together

I would argue that it was the other direction, in my experience the DevOps philosiphy was very similar in at the core to the agile philosophy; however it met the same fate as the agile movement. Everyone who was an "agile" consultant or "scrum master" found a new buzzword to declare themselves experts of and then use to go around doing a whole lot of nothing and generating impressive sounding promises, before moving onto the next gig.
