Sаm Shаm the Phаraоh is in a dreaded histоry class this term. But it's all оnline and so that makes it 10,000 times easier than having to go to a class and listen to boring history teachers drone on about Charlemagne or Hitler or somebody who's dead and doesn't matter any more. Yet Sam Sham's history teacher assigns lengthy history video lectures and some are like 45 minutes long. Sam Sham has no interest in watching these and taking notes, and so Sam Sham uses his spidey senses and downloads the video lectures' transcript. He then drops the transcript into ChatGPT, and then into Copilot. Just to be safe, he drops the same video lecture transcript into Gemini and Claude and then prints out all of these chatbot/AI summaries of the video lecture transcript. Sam Sham opens the quiz and discovers that none of these AI summaries help him to answer any of the questions. What did Sam Sham do wrong?

Berthа wаnts tо be а veterinarian оne day, but she's in this bоring history class (all online) as part of her undergraduate general education program. Bertha understands that history has nothing to do with veterinary science, and so she searches for all kinds of online help and shortcuts to doing her history assignments. But Bertha is also smart and realizes doing so violates the course policies outlined on the class syllabus. So she's sly about it and whenever she has to read a textbook chapter, she drops it into an AI or LLM/chatbot that spits out a 6-bullet point summary and Bertha decides to go with it for quizzes and exams. Her mean history teacher also assigns document analysis assignments that require writing, but Bertha doesn't need to learn how to write to practice veterinary science. So she puts all of the assigned primary sources into an AI to summarize these for her, and because Bertha is smart -- she gets Grammarly to write all of her sentences for her. After turning in several quizzes and document analysis assignments, Bertha learns that she's failing history class. What did she do wrong?
