Then I showed the class a PowerPoint which Notebook LM had generated for me from the two articles. (This took a few minutes, but no specific prompts from me at all.) The slick presentation glommed the two articles together with striking visuals, making a monolithic assertion out of different arguments and interpretations - an aggregated argument neither of our authors had made. The names of the two researchers appeared only once, in tiny print at the bottom of the title slide; their quite different forms of research, reasoning and argumentative contexts - and the openings for engagement and critique - all washed away.
I didn't spend long on it, though I pointed out various distortions and absurdities in the visualizations. (It gets a lot right, too, of course.) What did I hope the students learned? I told them that Notebook LM is very helpful opening up a single text, but that the work of critical engagement, weighing different sources, was beyond it. That's where you come in! In a week dedicated to the meaning and gift of plural perspectives and experiences, I hope they saw the threat in AI's mindless amalgamation.
