Cisco gives 27-year-old engineer unlimited AI tokens to rewrite 98% of the company's legacy code in 24 months
The initiative targets modernizing Cisco's aging systems. The project spans two years and involves rewriting nearly all existing code. The company's leadership has emphasized the importance of AI-driven efficiency.

Cisco has launched an ambitious initiative to modernize its legacy codebase by granting a 27-year-old engineer unlimited AI tokens. The project aims to rewrite 98% of the company's outdated code within 24 months. This move underscores Cisco's commitment to leveraging AI for large-scale software transformation, with the young engineer tasked with leading the effort.
The decision to entrust a young engineer with such a significant task reflects a shift in leadership strategy at Cisco. The company's president, Jeetu Patel, has emphasized the importance of tapping into fresh perspectives and technological expertise. This initiative aligns with broader trends in the tech industry, where AI is increasingly being used to streamline and optimize complex systems.
The project involves rewriting a vast majority of Cisco's legacy code, a process that is expected to take two years. The use of AI tokens is central to this effort, allowing the engineer to access powerful tools for code generation and optimization. This approach is expected to significantly reduce the time and resources required for such a large-scale rewrite.
The initiative may have broader implications for the tech industry, particularly in terms of cost, vendor lock-in, and governance. As companies increasingly rely on AI for software development, questions about long-term maintenance, integration with existing systems, and the potential for dependency on specific AI platforms are becoming more pressing. Market reactions will likely depend on the success of this pilot project and its scalability.
The outcome of this initiative could set a precedent for how large corporations approach AI-driven software transformation. If successful, it may encourage other companies to invest in similar projects, potentially reshaping the landscape of enterprise software development. The focus on AI as a tool for modernization highlights the growing importance of machine learning in the evolution of legacy systems.
