    特朗普强推“super intelligence”改名,AI行业术语之争升温

    特朗普签署行政令,要求尽可能避免使用“AI”一词,改称“super intelligence”,并将坚持使用“Artificial Intelligence”的人称为“THE ENEMY”。美国AI标准与创新中心(CAISI)已更名为CAISSI,司法部新闻稿也改用该说法。文章指出,“superintelligence”一词由 Nick Bostrom 在2014年同名书中普及,本指可能超越人类思维的高级AI,而非整个AI类别,强行推广反而削弱企业用该词宣传新产品的能力,且国会与现有法律仍在使用“artificial intelligence”。

Trump adopting “super intelligence” might seem good for companies that had already hitched their wagon to superintelligence, including Meta and Microsoft.
