Screen 1.2: Lex Studio Response
Paul Hegarty's first engagement • Skeptical Testing Phase • Critical conversion moment
User Testing Context
Paul just uploaded his 52-minute CS193p lecture on MVVM architecture. He's curious but guarded — wondering if an AI can understand teaching nuance. This response determines if he explores further. Three versions below test different approaches.
CS193p Lecture Recording
Paul Hegarty's MVVM Architecture Session
I watched the entire lecture. Here's what I noticed:
The layered explanations.
You introduced MVVM three different ways — first the diagram, then the analogy to a restaurant (kitchen, waiter, diner), then live code. Each layer built on the last. You said the concept needs to land before the implementation makes sense.
The deliberate pauses.
When you got to the ObservableObject protocol, you stopped coding entirely. Looked at the camera. Let the silence sit for a few seconds before asking why @Published matters. You're not filling time — you're creating space for thinking.
The NeXTSTEP callbacks.
Three times you referenced how something worked in the old days — delegates, target-action, NotificationCenter. Not nostalgia. You're showing students that patterns have ancestors. The new thing isn't magic, it's evolution.
The live mistakes.
You left in the typo at 34:12. Didn't edit it out. Walked through the error message like it was curriculum. You said debugging is half the job, might as well teach it. Most professors would reshoot that.
I'm not going to tell you how to structure your teaching. 15 years of CS193p speaks for itself. But I'm curious about the decisions behind the decisions — the pedagogical instincts that might be harder to articulate than demonstrate.
A few things I'm curious about:
Version A Design Notes:
- ~200 words — comprehensive observation coverage
- Four distinct sections mirror Paul Hegarty's content structure
- Uses their exact phrases (highlighted) to show attentiveness
- Ends with explicit non-prescription: "I'm not going to tell you..."
- Risk: Might feel like a report rather than a conversation
Current Persona: Paul Hegarty (University Professor)
Version Comparison
A: Full Observations
~200 words. Comprehensive. Shows Lex paid attention to everything. Risk: might feel like a report.
B: Short & Punchy
~120 words. Same themes, tighter. Matches his energy. Risk: might feel too casual.
C: Single Hook
~100 words. Leads with turquoise mystery. Intriguing. Risk: ignores the rest of the tour.
