Your steroids comparison made me think of Cal Newport's recent blog post[1] where he argues that AI is making us lazy. He quotes some researchers who hooked people up to EEG machines then had them work. The people working without AI assistance incurred more brain "strain" and that's probably a good thing.
But even he doesn't think AI shouldn't be used. Go ahead and use it for stuff like email but don't use it for your core work.
