To add on to what others have said, vibe coding is ushering in a new golden age for black hat hackers. If someone is rely entirely on AI to generate code they likely don't understand what the code they have is actually doing. This tends to lead to an app that works correctly for what the prompted specified but behaves badly the instant it has to handle anything outside of the prompt, like a malformed request or data outside the prompted parameters. As a result these apps tend to be easy to exploit by malicious actors, often in ways the original prompter never thought of.
