Impromptu: Amplifying Our Humanity Through AI be slower, less comprehensive, and working at a great dis- advantage. For example, GPT-4 is a research tool you can use to quickly get an overview on supply chain management issues in the COVID- 19 era—or to plan a week-long vacation itinerary to Patagonia that takes into account that you’re a vegan who enjoys moder- ately challenging hikes. Along with enabling a new kind of highly contextualized search, GPT-4 is also an extremely versatile brainstorming and pro- duction aid. You can use it to help you write a wedding toast, a job offer, a novel in verse. You can use it to figure out how to turn the leftovers in your fridge into a tasty meal. Whatever your skill level at a given task, GPT-4 can potentially amplify your abilities and productivity, so it’s equally useful to beginners, experts, and everyone in between. Given a request for any sort of information that you might ask a human assis- tant for, GPT-4 can come back instantly with an answer that is likely between good and excellent quality (though also with a non-zero chance of completely missing the mark, as we’ll see). Developers, I realized, would soon be adding GPT-4 to thou- sands of existing apps and building thousands of new apps around it. It is, all said, a technology that deftly leverages some of our most significant technologies from the last thirty years—includ- ing the internet, mobile, cloud computing, and data analytics— to put the protean power of always-on AI into the hands of hun- dreds of millions of people. Sounds a little bit like the start of a new world, doesn’t it? 6
