It’s a great episode of TV because Data is a main cast character who is obviously conscious. We know before the episode starts who is right and who is wrong in this particular argument. This episode is not about consciousness, it is about civil rights: resisting bigotry and power.
Note that the episode is NOT about the ship’s computer. They all know it’s not conscious, despite also being a machine that can converse and do things.
Our LLMs are like the ship’s computer.
