This talk is different from his others because it's directed at aspiring startup founders. It's about how we conceptualize the place of an LLM in a new business. It's designed to provide a series of analogies any one of which which may or may not help a given startup founder to break out of the tired, binary talking points they've absorbed from the internet ("AI all the things" vs "AI is terrible") in favor of a more nuanced perspective of the role of AI in their plans. It's soft and squishy rhetoric because it's not about engineering, it's about business and strategy.
I honestly left impressed that Karpathy has the dynamic range necessary to speak to both engineers and business people, but it also makes sense that a lot of engineers would come out of this very confused at what he's on about.
