You know that ancient codebase from 2012 that's held together with duct tape, jQuery, and prayers? The one where variable names are single letters and every function is 500 lines long? Yeah, AI takes one look at that spaghetti monster and absolutely demolishes you with its "feedback." It's like asking a fitness trainer to review your diet when you've been eating gas station hot dogs for a decade. The AI doesn't just suggest improvements—it goes full Gordon Ramsay on your code. "Why are you using var ? What's this callback hell doing here? IS THIS A GLOBAL VARIABLE?!" Meanwhile, you're just sitting there getting absolutely pummeled by suggestions to refactor everything into microservices with TypeScript, proper error handling, and—*gasp*—actual documentation. The legacy code fights back harder than you expected, and you realize you've bitten off way more than you can chew. Should've just left it alone and pretended it didn't exist like everyone else on the team.
