I believe the primary reason platform engineering is trending is that the original "you build it, you run it" promise of DevOps has become a burden for many developers. While the idea of owning the full lifecycle sounds great in theory, the reality is that developers are now expected to be experts in Docker, Kubernetes, Terraform, and various security protocols on top of writing their actual application code. I see this as "DevOps fatigue." This perspective suggests that developers want to get back to solving business problems rather than fighting with infrastructure. Transitioning to platform engineering allows an organization to centralize the complex operational work while giving developers a clean, simple interface to get their jobs done. I feel that the industry is finally admitting that asking every coder to be a part-time systems administrator was a mistake that led to slower release cycles and increased frustration. Platform engineering is trending because it offers a more realistic and sustainable way to achieve the speed that DevOps promised without burning out the engineering team.
