Documented Proof That I Sleep
By Cristiano Pierry
A week of Codex logs turns heavy AI usage into a visible rhythm, including the rare hours without prompts.

There is now documented proof that I do, in fact, sleep.
This is the frequency of messages I sent to Codex over the last seven days. As you can see, there is a suspiciously quiet window in the middle of the night where no prompts were sent, no tests were requested, no bugs were challenged, and no agents were asked to “just quickly check one more thing.”
P.S. This is actual usage data from my Codex logs, just turned into a slightly more presentable chart.
This writing reflects my personal perspectives on product management, AI, and content discovery. It does not represent the official position of my employer or any affiliated organization.
