但是利用光来处理信息还很复杂，要求有合适的材料和需要有比传统晶体管能力更强的激光器。
But using light to process information is tricky, requires exotic materials and lasers that demand more power than conventional transistors.
如果机器和人都没有接收到他们需要的信息，即使拥有最大功率的激光机和最有效的原材料处理系统也是无济于事的。
The most high-powered laser and efficient material handling system don’t count for much if both machines and people can’t access the information they need.
在生物相容的装置中嵌入一个内部信息处理器，然后几个这样的装置将被包合进容纳有电线的高分子材料中，这些电线伸展时可达1.22毫米。
An internal processor is inserted in a biocompatible device, then a few of these devices are sewn up together into a polymer containing electronic wires that stretches a short 1.22 mm across.
