It has nothing to do with your level of knowledge or experience as a programmer. It has to do with how you learn: https://www.hup.harvard.edu/books/9780674729018

To learn effectively you need to challenge your knowledge regularly, elaborate on that knowledge and regularly practice retrieval.

Building things solely relying on AI is not effective for learning (if that is your goal) because you aren’t challenging your own knowledge/mental model, retrieving prior knowledge or elaborating on your existing knowledge.
