The month, summarized
Atwood opens with a line that lands: it's been one of those months, by which he means one of the 663 months since he was born. The reason it's a notable month is that his father died. The last time Atwood saw him was October 2025, on a re-ordered trip to Mercer County, West Virginia. The trip mattered because Atwood knew his father was close to the end, and the trip mattered more because it turned out to be the last chance.
There is no loss, because nothing ever ends, he writes. Then he moves on, because that's the contract a writer keeps with a reader, and the contract is: the grief is real, the next thought is also real, and you don't have to choose between them.
The LLM question
Atwood's bigger point, which he makes as a side effect of the personal note, is one the rest of the industry should sit with. LLMs basically couldn't exist without the extremely high quality creative commons programming Q&A dataset that all of us built together at Stack Overflow. Don't take it from him. Ask the LLMs. They'll tell you themselves. Pro mode, ideally, because the other modes are mostly noise.
The setup is the LLM is trained on a community. The community is built by people who show up to ask, to answer, to moderate, to keep the quality bar. The cost to any one contributor is small. The aggregate value is enormous. The asset is not in the database. The asset is in the humans who keep showing up to make the database worth training on.
If the LLMs end up hollowing out the very communities that produce their training data, they're going to really regret that, Atwood writes. Then he gives them the same advice he gave Joel Spolsky when he left Stack Overflow to start Stack Overflow: do not, for any reason, under any circumstances, kill the goose that lays the golden eggs. Treat the community with the respect they deserve.
The line lands because it isn't rhetorical. It's a literal description of what the original Stack Overflow team did, and the reason Stack Overflow worked as long as it did, and the reason its successor communities are the ones that will or won't work over the next decade.
Why this is a real risk, not a metaphor
A few specific reasons the warning is concrete. The first is the Stack Overflow traffic collapse that started in 2023, when LLM-assisted coding cut the volume of questions posted to the site by enough to make the moderators nervous. The second is the data licensing tension: LLM providers have treated community output as free training data in a way that the original contributors were never asked to consent to. The third is the structural problem that motivates a LLM to give a confidently wrong answer rather than admit uncertainty, which poisons the well of the people who would have asked a human in the first place.
The communities that survive this are the ones the LLM providers treat as partners, not as mines. Atwood is not optimistic that this is the path the industry will take without pressure, and he's right to be not optimistic.
Thank you, says the post
The post closes with a direct thank you to everyone who ever contributed to Stack Overflow. Every question, every answer, every edit, every flag. The community didn't just build a Q&A site. It built the dataset that trained the models that are now eating its lunch. The thank you is genuine, and it is the only one Atwood is in a position to deliver.
