translation.en: So Homo sapiens, the first technology-creating species, the species that combined a cognitive function with an opposable appendage -- and by the way, chimpanzees don't really have a very good opposable thumb -- so we could actually manipulate our environment with a power grip and fine motor coordination, and use our mental models to actually change the world and bring on technology.
translation.zh: 所以智人，第一个创造科技的物种， 把认知功能 和大拇指运动结合的物种 -- 顺便提一下，黑猩猩其实没有一个非常好的大拇指 -- 所以我们可以用很强的握力来操纵我们的环境 和好的动作协调， 和用我们的心智模式来真正改变世界 而且带来科技。
