Andrej Karpathy. Karpathy walks through his actual day-to-day use across ChatGPT, Claude, Gemini, Grok, and Perplexity, screen-sharing live conversations rather than polished one-shots. You see when he reaches for a follow-up, when he switches models mid-thread, and when he abandons a line and starts over — exactly the iterative loop the article describes, modeled by someone who builds these systems for a living.

AI Expert note

Don't mine it for techniques — the value is watching when he follows up, switches models or starts over, which is exactly the iterative habit the article argues for. Fine to watch in chunks.

What you should get from this

You can recognize when to follow up, when to switch models and when to start a fresh conversation, calibrated against real day-to-day usage.

Watch or know first

None — watchable cold; the only real barrier is the two-hour-plus runtime.
