Articles, social media posts and photos are now often AI generated. There is going to be a certain percentage of today's students that will graduate "knowing" blatantly wrong things an LLM told them. These things will eventually make their way to books and society.
One thing the scientific community never got around to accepting themselves and admitting to the public is how much of the learning is trust-based rather than fact-based. Nobody can prove everything from the ground up, you need to put your trust into your predecessors. Eventually you'll have the capacity to doubt and check a percentage of what they said, but not everything. When this circle breaks and you don't know if your lecturer is for real or just parroting LLMs we'll be in trouble. The "financialized" ultra-competitive environment of higher education doesn't help with that either.
