Using Gemini 2.5 Pro, they accelerated reverse engineering, creating validated "blueprints" of functionality in just two weeks. The pilot showcased AI's potential to drastically reduce time and risk in modernizing opaque systems while balancing speed with validation.</p> <i>By Matt Foster</i> Legacy Code Artificial Intelligence Generative AI Reverse Engineering Architecture & Design Development news Tue, 16 Sep 2025 08:00:00 GMT https://www.infoq.com/news/2025/09/tw-blackbox/?utm_campaign=infoq_content&utm_source=infoq&utm_medium=feed&utm_term=Reverse+Engineering Matt Foster 2025-09-16T08:00:00Z /news/2025/09/tw-blackbox/en
