The goal of this chapter is to discuss AI's role in the more intricate layers of your system. AI, as mentioned, does not merely rewrite code, but it can transform and restructure code bases and make suggestions, even implement them, to the structural layout of your code. Even if humans do it, it can be pretty destructive, but is mitigated by revision control technology. Before we dive into that, it is critical to understand that AI can, and will, make mistakes. We will first discuss AI's hallucinations and what they really mean and then move on to the abilities of AI. It is essential to understand the shortcomings of AI when you let it loose on your code base.
