We do programmers a disservice when we act as if the conversation about the growing threat of legacy code begins and ends with COBOL. A whole generation of software engineers are spending their careers making the problem worse by outsourcing all but the most unique aspects of their applications to armies of libraries, plugins and modules that they are powerless to monitor let alone update.

The real horsemen of the legacy apocalypse is the depth of the dependency tree. Modern software development stacks abstraction on top of abstraction. If the left-pad incident of 2016 proved nothing else it demonstrated that even experienced engineers will YOLO dependencies on to their applications if given the infrastructure to make installing them easy. Modern developer environments are a veritable candy store of cheap and convenient dependencies.
