I think I speak for all of us when I say get fucked, Sam https://fortune.com/2023/05/05/openai-ceo-sam-altman-remote-work-mistake-return-to-office/
So, the article was paywalled, why I did not read it. However, it seems from the opening blurb that he is talking in the context of "start-ups"?
From that POV, I think he might have a point. 12 or so people in a new company working to get it started, I imagine a shared location would be beneficial in that context.
Most of us do not work in start-ups, so can disregard advice on how to run one.
