不错啊

没看懂到底是干什么的？

In my opinion, this novel just want to express, just as the subtitle, "a word to the wise".
"Some unknown creatures are speaking an unknown language in a sealed black box: would you dare to knock at the door and say hello?"
"We certainly will never understand what they are talking about if we don't knock on the door of that sealed container and say hello first.”
In our daily life, the best way to know something new is just having a contact with it. Xia delivers this scientific conception successfully in the story.

小说很有趣。其中有一句话：“机器人不得伤害人，同时也要保护自己。”
