tl;dr: Developers build deep trust in tools like Vim, Emacs, and IDEs through predictability and muscle memory, but agentic AI coding tools break this model—Stack Overflow's survey shows usage rising (76%→84%) while trust falls (40%→29%). AI shifts the bottleneck from writing code to reviewing and validating it, exposing flaws in existing SDLC processes that new tooling alone can't fix. Rebuilding trust requires explicit human ownership (not "human-in-the-loop"), better context/memory systems for agents, enforcing DRY principles, and knowing when deterministic code beats non-deterministic LLMs.
