More than 1,000 Amazon employees have signed an open letter to leadership, including CEO Andy Jassy, warning that the company's rapid and aggressive push into artificial intelligence could cause significant harm. The letter, organized by the activist group Amazon Employees for Climate Justice (AECJ), expresses concerns that the current "all-costs-justified" approach to AI risks damaging democracy, eliminating jobs through automation, and harming the planet due to the increased environmental footprint of data centers. The employees are calling for a more responsible and slower rollout of AI technologies that prioritizes ethics, sustainability, and human welfare over pure profit and automation. This public display of internal concern comes as Amazon continues to invest heavily in AI, including a reported $150 billion plan for new data centers, and follows significant job cuts within the company. No market reaction to this letter has been reported.
