The “ism” requires something beyond simply recognizing the distinction, which OP didn’t do. Its not “elitism” to recognize that, for most people, the world around them might as well be magic. “Ism” would be if they went further and said we should treat people better if they’re higher IQ. In fact, the point was the opposite. AI could erase the class distinctions that exist for the cognitive elite.

Imagine the response of the general population to the kinds of arguments you all are making. "Where were you when our jobs were changed out of existence?" They will be properly outraged by the perceived intellectual elitism, the implicit argument "this is different, because we are the ones that matter".
