用户为实体硬件付费的意愿，天然高于为虚拟服务订阅付费，一个售价299美元的智能戒指，其价值是具体、可感知、且符合传统消费心智的，这为创业公司提供了最直接的启动现金流。
如人形机器人的手指空间极其有限，却需要容纳驱动、传动、感知等多重功能。传统减材制造在面对如此微小的复杂部件时，往往面临“刀具下不去、结构做不出”的困境。高精度金属打印突破了这一物理限制，能在极小空间内集成复杂的内部传感结构与��性体梁，将复杂的内部油路、电路通道与弹性体结构一体化成型，使显微级的力觉感知成为可能。，详情可参考新收录的资料

For example, a virtual machine can be used to take code designed for one type of CPU and run it on a different type of CPU. This is often called an emulator, and they can be useful when it isn't possible to recompile the code for the new CPU (such as if the original program is a closed-source video game for a proprietary game console but you want to run it on a desktop PC).。业内人士推荐新收录的资料作为进阶阅读
