Nah. Nothing has changed. To offload the work to an agent and make it a productivity gain it is exactly the same as using a framework, it's a black box portion of your system, written by someone else, that you don't understand.
Unless you are quite literally spending almost the same amount of time you'd spend yourself to deeply understand each component, at which point, you could write it yourself anyway, nothing has changed when it comes to the dynamics of actually authoring systems.
There are exceptions, but generally speaking untempered enthusiasm for agents correlates pretty well with lack of understanding about what engineering software actually entails (it's about relational and conceptual comprehension, communication, developing shared knowledge, and modeling, not about writing code or using particular frameworks!)
EDIT: And to be clear, the danger of "agentizing" software engineering is precisely that it promotes a tendency to obscure information about the system, turn engineers into personal self-llm silos, and generally discard all the second-order concerns that make for good systems, resilience, modifiability, intelligibility, performance.
