The "new school" is not about operations doing it all themselves, or about a new "devops" position that does both dev and ops. It's about greater cooperation between the team that's developing the application ("dev") and the team that supports it on a day to day basis ("ops"). It's not a new idea, but that doesn't stop it being useful.

If you're working on a team that is responsible for both then devops isn't a useful concept - you're probably doing it already. Many people are not so lucky.
