与此相对，Hugging Face 首席执行官克莱姆・德兰格提出了不同见解。他认为当前不存在全面的 AI 泡沫，而是特定的"大语言模型泡沫"，并预测这个泡沫 可能在明年破裂。他指出，未来趋势将是从追求通用大模型转向开发更多专用化的小型模型，这种转变将更符合实际商业需求。 【太平洋科技快讯】11 月 19 日消息，谷歌母公司 Alphabet 首席执行官桑达尔・皮查伊近日在接受 BBC 采访时指出，当前人工智能投资热潮中存在一定程 度的"非理性"成分。他警告称，若 AI 泡沫破裂，所有企业都将受到波及，无一能够幸免，即便是拥有全栈技术优势的谷歌也不例外。这番表态正值 AI 公司 估值持续飙升之际，引发了市场对行业过热的高度关注。 然而，AI 的快速发展也带来了严峻挑战。皮查伊特别指出，AI 已占全球电力消耗的 1.5%，这种"巨大"的能源需求可能成为经济发展的瓶颈。他承认公司气 候目标因此受到影响，但承诺仍将坚持 2030 年净零排放目标。在就业方面，他认为 AI 将是"最具变革性的技术"，善于运用 AI 工具的人将在各个职业中脱 颖而出。 皮查伊将当前状况与 1996 年互联网泡沫时期的"非理性繁荣"相提并论 ...
