I have what you call "significant engineering experience", decades of it to be precise and have designed and developed many complex products successfully used in various industries.
I do not need to "shift my perspective" since I do use agents to the degree that I need and it helps help me very much. I am way more productive with them.
Generated code is still not perfect disregarding of any particular model (I have access to all). I have to watch and fix, sometimes by supplying more precise specs, sometimes asking to rewrite piece of code in such and such manner using this and that structures.
