This document discusses the future of DevOps and some challenges it faces. It notes that while DevOps started as a grassroots movement, it has now been commercialized by many vendors. This risks ruining the original ideas by over-emphasizing tools and certifications. Adoption in large enterprises also faces challenges like change resistance. However, DevOps still has a future if the focus remains on culture change rather than just tools. Continuous education is needed to teach its principles to new people and help organizations embrace new technologies over the long multi-year journey of transformation.
