Engineering is about creating something that serves a purpose, while operating within a set of constraints. Part of that is realizing that "100% correct/reliable in all circumstances" is an unrealistic goal, since implementation time and cost is one of those constraints.
A good engineer will acknowledge this tradeoff between robustness and cost and behave accordingly. For example, if you're working on safety critical or very foundational systems like OSes, medical tech, etc you should bias very heavily in favor of robustness. If you're not, this can easily be an act of overengineering. The engineer's job is to find the right spot along the cost-correctness curve for the thing they are building.
This has always been true, and LLMs just change certain parts of the equation. For example, code writing is far less of a bottleneck than before, so "we can just try with a throwaway impl and see if this works" is suddenly economically viable. It also turns out that many things, in practice, don't need to be as correct as some of us may have believed.
We can still enjoy making quality things, but doing so is often an act of artisanship rather than engineering.
