So you thought AI-generated code and fancy new developers would just replace that crusty legacy system held together by duct tape and prayers? Think again. That Porsche with the door literally falling off still runs, still gets the job done, and somehow survives rush hour traffic. Meanwhile, Claude and the junior dev are stuck in gridlock wondering why their beautiful, modern solution can't handle production. Legacy code might look like a disaster from the outside, but it's battle-tested, knows every edge case, and has survived migrations that would make grown developers cry. Sure, the door's hanging by a hinge, but that Porsche's engine? Still purring. Your shiny new microservice? Crashed on deploy.
