U are arguing against a person who isnt there. I also have done similar and my mind was not thinking specifically prompt the whole output. I think people have this kneejerk to anything that isnt total negativity of ai in the creative space. It is only a tool.
Beyond that, they can also be more or less effective for a variety of purposes.
I spent decades to achieve solid competence at a few different skills, and my experience of genAI thus far is that it can easily give the user the delusion of mastery, ensuring the user does not develop true skills, trapped in the false belief that they can do everything they want to or ever would want to.
The process of struggling to learn new skills showed me new worlds of possibility I would never have discovered or explored without first developing those skills.
There are very legitimate reasons why so many artists and musicians hate genAI.
