Lately, this topic is controversial, the AI use, and a writer demanding upfront payment. On the other hand, many writers have been scammed by students who refuse to pay after work receipt. As a student, I would recommend you stick to your writer. If you bump into a real one, keep them because they are not easy to find, especially in this AI ethical issue. I experienced this problem sometime last year when a masters student, business admin, refused to clear the payment after we successfully achieved A grade in all the courses. I used the trick of letting them pay in bits, say weekly to compesante weekly tasks. As a result, I did not lose much, but still he broke my heart. Even though I let it slide, I warned him never to do such a thing to anyone, as it can be detrimental to his classes.
