The AI company Anthropic insisted that it could not remove safeguards preventing the Department of Defense from using its technology for domestic mass surveillance or autonomous lethal weapons. The Pentagon said it had no interest in such uses – but that such decisions should not be made by companies. Outrageously, the administration has not just fired Anthropic but blacklisted it as a supply-chain risk. OpenAI stepped in, while insisting that it had maintained the red lines declared by Anthropic. Yet in an internal response to the user and employee backlash, its CEO Sam Altman acknowledged that it does not control the Pentagon’s use of its products and that the deal’s handling made OpenAI look “opportunistic and sloppy”.
展望未来，21的发展趋势值得持续关注。专家建议，各方应加强协作创新，共同推动行业向更加健康、可持续的方向发展。
