正如卡马克所观察到的，光纤传输的增长曲线可能比DRAM更有利，尤其是在元件小型化速度放缓的 情况下。但他承认存在一个主要障碍——200公里长的高品质光纤成本高昂，而且维持传输所需的放 大器和数字信号处理器可能会抵消任何节能效果。 这场辩论甚至转向了推测。埃隆·马斯克设想了基于真空的光数据传输——本质上是在自由空间中进 行激光存储——尽管这个想法目前更像是科幻小说，而非工程方案。 公众号记得加星标⭐️，第一时间看推送不会错过。 未来，光而非硅或许将定义人工智能存储和调用知识的方式。约翰·卡马克（John Carmack）——这 位因参与《毁灭战士》（Doom）和Meta虚拟现实项目而闻名的工程师——最近提出了这一想法，他 建议使用光纤环路作为人工智能模型的高速数据缓存。他在X论坛上的简短帖子引发了一场激烈的技 术讨论，研究人员和技术专家们对经典计算机理论与现代光网络技术的融合充满兴趣。 这个思想实验始于一个数字。单模光纤现在可以以每秒 256 太比特的速度传输 200 公里的数据。基 于这一容量，卡马克估计，在任何给定时刻，电缆中大约存储着 32 GB 的信息。 卡马克建议不要将此视为单纯的数据管道，而是将循环 ...
