It's a rebuttal in the same way that saying the Vulcans in Star Trek use AI in their classrooms. Star Trek is a fictional story in a fictional universe that doesn't have to follow the laws and rules of science, society, reality, etc for the sake of telling a story that fans will want to follow.

I think you miss the point of Star Trek, it, even more than most SF, isn't "really" about the future fictional or otherwise -- it is using the tropes of SF to make commentary on our society through analogy. That being said, I'm not sure the OP recognizes that Vulcans aren't entirely presented positively on the show -- they are generally viewed as missing part of life with their lack of emotions.
