A Coder Considers the Waning Days of the Craft

I had gathered as much from Ben, who kept telling me about the spectacular successes he’d been having with GPT-4. It turned out that it was not only good at the fiddly stuff but also had the qualities of a senior engineer: from a deep well of knowledge, it could suggest ways of approaching a problem. For one project, Ben had wired a small speaker and a red L.E.D. light bulb into the frame of a portrait of King Charles, the light standing in for the gem in his crown; the idea was that when you entered a message on an accompanying Web site the speaker would play a tune and the light would flash out the message in Morse code. (This was a gift for an eccentric British expat.) Programming the device to fetch new messages eluded Ben; it seemed to require specialized knowledge not just of the microcontroller he was using but of Firebase, the back-end server technology that stored the messages. Ben asked me for advice, and I mumbled a few possibilities; in truth, I wasn’t sure that what he wanted would be possible. Then he asked GPT-4. It told Ben that Firebase had a capability that would make the project much simpler. Here it was—and here was some code to use that would be compatible with the microcontroller.
