Students cheating with LLMs show more a weakness of a system than anything else. Rich folks had other people make assignment for them for ages, now this got democratized. The educational institutions are mostly disinterested in really doing what they should do to teach critical thinking and understanding if students really understood. To check the home made assignments is a small part of that (in theory). It's not LLMs, is terrible schools.
I studied CS and Philosophy in college. The philosophy department at the time was struggling to get people to declare so they started a campaign with the slogan “Thinking of a major? Major in thinking”. Which I’ve always thought was both clever and accurate. Such departments become more valuable as the harder skills are more automatable. I doubt that will translate into more philosophy majors but one can dream.
