AI as coder, reports from the trenches

Clive Thompson, Coders Coded Their Job Away. Why Are So Many of Them Happy About It? NYTimes, Mar. 12, 2026.

He and Brennan-Burke, who is 32, are still software developers, but like most of their peers now, they only rarely write code. Instead, they spend their days talking to the A.I., describing in plain English what they want from it and responding to the A.I.’s “plan” for what it will do. Then they turn the agents loose.

A.I. being A.I., things occasionally go haywire. Sometimes when Claude misbehaves and fails to test the code, Ebert scolds the agent: Claude, you really do have to run all the tests.

To avoid repeating these sorts of errors, Ebert has added some stern warnings to his prompt file, the list of instructions — a stern Ten Commandments — that his agents must follow before they do anything. When you behold the prompt file of a coder using A.I., you are viewing a record of the developer’s attempts to restrain the agents’ generally competent, but unpredictably deviant, actions.

A coder is now more like an architect than a construction worker.

I looked at Ebert’s prompt file. It included a prompt telling the agents that any new code had to pass every single test before it got pushed into Hyperspell’s real-world product. One such test for Python code, called a pytest, had its own specific prompt that caught my eye: “Pushing code that fails pytest is unacceptable and embarrassing.”

Embarrassing? Did that actually help, I wondered, telling the A.I. not to “embarrass” you? Ebert grinned sheepishly. He couldn’t prove it, but prompts like that seem to have slightly improved Claude’s performance. [...]

Computer programming has been through many changes in its 80-year history. But this may be the strangest one yet: It is now becoming a conversation, a back-and-forth talk fest between software developers and their bots.

This vertiginous shift threatens to stir up some huge economic consequences. For decades, coding was considered such wizardry that if you were halfway competent you could expect to enjoy lifetime employment. If you were exceptional at it (and lucky), you got rich. Silicon Valley panjandrums spent the 2010s lecturing American workers in dying industries that they needed to “learn to code.”

Now coding itself is being automated. To outsiders, what programmers are facing can seem richly deserved, and even funny: American white-collar workers have long fretted that Silicon Valley might one day use A.I. to automate their jobs, but look who got hit first! Indeed, coding is perhaps the first form of very expensive industrialized human labor that A.I. can actually replace.

Why programmers like their AI coders:

The enthusiasm of software developers for generative A.I. stands in stark contrast to how other Americans feel about the impact of large language models. Polls show a majority are neutral or skeptical; creatives are often enraged. But if coders are more upbeat, it’s because their encounters with A.I. are diametrically opposite to what’s happening in many other occupations, says Anil Dash, a friend of mine who is a longtime programmer and tech executive. “The reason that tech generally — and coders in particular — see L.L.M.s differently than everyone else is that in the creative disciplines, L.L.M.s take away the most soulful human parts of the work and leave the drudgery to you,” Dash says. “And in coding, L.L.M.s take away the drudgery and leave the human, soulful parts to you.”
