You do. And so does your non-technical mother (or a friend of your mother).

The impact of the iPhone and its competitors is felt everywhere, it diffused into every domain of people's lives. Think: the whole of social media was pretty much enabled by smartphones.

Or a more pedestrian, random example: every day I go to the office, I see endless store managers, restaurant managers, etc. walking around their store, making photos to upload to HQ. But this is merely a symptom - the actual consequence is the change in busines structure. It's because smartphones make this easy, that it makes franchise and subcontracted businesses more viable, because it's easier for the HQ to micromanage more semi-independent subordinates.

There are many, many more examples like this everywhere you look. Which is why I'm inclined to agree with Karpathy: computers, iPhones, LLMs, are all the same thing - it's just the more notable manifestations of how we've been staying on 2% growth exponential curve for many hundreds of years now, and why we'll continue to stay on this curve.

But the caveat is: that curve is getting steep enough that the world is starting to transform faster than we can handle.
