Ep. 3 - Sarah Williamson: The 70/30 Line and the Limits of a Tool Without a Soul

What do graduate students and Disney tourists have in common? According to Dr. Sarah Williamson, they both need a better roadmap than a robot can give them.In this episode of The Line, Sean and Matthew open with a conversation that felt inevitable: Anthropic's very public refusal to allow the Department of Defense to use Claude for autonomous weapons systems — and the wave of ChatGPT cancellations that followed. It's a moment that forces a question we keep returning to on this show: not just how we use AI, but what we're participating in when we do.Then we sit down with Dr. Sarah Williamson — student affairs educator, graduate instructor at West Chester University, and the force behind a Disney travel advisory Instagram account that's racking up 25,000–30,000 monthly views in under four months. Sarah doesn't just use AI; she's built what she calls a "smart house" — a carefully layered stack of tools (Gemini, NotebookLM, TravelJoy Co-pilot, and more) that she's trained to carry her voice, her teaching style, and her values.She talks about using Gemini conversationally to cut 800 words from a publication piece in 27 minutes — not by having it rewrite the piece, but by having it point her toward redundancies so she could make the cuts herself. She talks about using NotebookLM to cross-check the equity of her own grading across 20+ student papers. She talks about how AI can give her a starting framework for planning trips for neurodivergent kids — and why the actual conversation with the family is irreplaceable.But the moment that stops the conversation is her phrase: AI doesn't have a soul.Sean and Matthew spend the debrief unpacking that. What does it mean to say something lacks a soul when people are forming genuine emotional connections with their AI tools? Matthew talks about the idea of putting a deceased mentor's writings into NotebookLM and what it would mean to "have a conversation" with them. Sean raises the AI Heidegger GPT they've experimented with, and what it means to be struck by a response that could have beensomething Heidegger would say.And then there's the question of time — picked up from a thread in a previous episode — about the felt unfairness when you can tell someone spent 10 seconds generating something you're spending 5 minutes reading. Is AI-detection fundamentally a phenomenology of reciprocal effort?Also in this episode: the line between ethical AI adoption and complicity, sustainability and water usage, why the travel industry is moving faster than higher education, and why a viral Instagram comment about Harry Potter's 11th birthday might be the best argument for keeping your own voice.Sarah's 70/30 rule is one of the cleaner frameworks we've heard on the show. The tools can do the heavy lifting. But the soul of the work — the connection, the presence, the meaning-making — that's still ours.Dr. Sarah Williamson is a veteran student affairs educator and graduate instructor at West Chester University, bringing nearly 20 years of experience—including leadership as a senior student affairs officer—to the classroom.
