New  technology usually did require a skilled laborer, which was something most slaves weren't.

新技术通常确实需要熟练的工人，而大多数奴隶则不需要。

薪水通常更高，至少与同等技能的工人相比是这样，但他们也几乎不需要体力劳动。

So what they decided to do is to create a robot where an individual with maybe only one year of experience could operate a machine that could perform the tasks that a skilled laborer with 20 years of experience could perform.

所以他们决定做的是创造一个机器人， 一个可能只有一年经验的人可以操作一台机器， 它可以执行一个有 20 年经验的熟练工人可以执行的任务。
