According to Business Insider, Amazon plans to replace its Trainium 2 systems with Trainium 3 servers at its data center in Indiana, even though Trainium 2 chips only became fully available in December 2024. This move contradicts Amazon CEO Andy Jassy's previous statement that servers have a lifespan of "at least five to six years." Amazon had previously shortened the estimated useful life of some servers and networking equipment from six years to five years, effective January 2025, due to accelerated technological advancements, particularly in AI and machine learning. This led to the early retirement of some equipment, resulting in an estimated reduction of approximately $700 million in operating income and accelerated depreciation and related expenses of about $920 million in 2025. This rapid turnover could impact the economic benefits of Amazon's substantial investments in AI infrastructure.
