My remark was to highlight that buzzwords are often used for "me-too" ankle-deep conversations/articles. Whether someone calls it Devops, or Systems Engineering, makes no difference to me. However, I favor pragmatic conversations about the topic, rather than buzzword bingo.
Examples include: "MongoDB sucks.", "Everyone should use Docker", and "What? You mean you're not using Kubernetes for your CRUD app?"
Basically, blanket statements that accomplish nothing more than to send social signals.
So it's healthy to embrace it as counter-balance to the constant hype.
(Besides, whether something is "real" or "solid" I think can mostly be answered in hindsight -- when it's mature enough and tested enough. In which case calling only things in the past solid is prudent).
