AI Coding Tools Create Legacy Code Even as They Modernize Old Systems
Legacy refactoring of code older than 12 months has dropped 74% since 2023 as developers use AI to build new features instead. Meanwhile, each 25% increase in AI usage adds 7.2% more system instability, per Google's DORA report. Enterprise tools from Anthropic and others are helping modernize 25-year-old systems, but daily AI-generated code is creating new tech debt.

The real story is that AI is solving one legacy problem while quietly creating another, and the industry's focus on speed over maintainability will come due.
