I guess if you're generating some script to run on your own device then sure, why not. Vibe a little script to munge your files. Vibe a little demo for your next status meeting.
I think the tip-off is if you're pushing it to source control. At that point, you do intend for it to be long lived, and you're lying to yourself if you try to pretend otherwise.
I see this kind of retort more and more and I'm increasingly puzzled by it. What is the sector of software engineering where we don't care if the thing you create works or that it may do something harmful? This feels like an incoherent generalization of startup logic about creating quick/throwaway code to release early. Building something that doesn't work or building it without caring about the extent to which it might harm our users is not something engineers (or users) want. I don't see any scenario in which we'd not want to carefully scrutinize software created by an agent.
