Elon Musk is building Cybercab and getting ready to catch a Starship out of the air, and on most nights he is still on X past 2 a.m. I wanted to see what that looks like as data. So I took every post and reply from his account over two weeks, reposts included, from October 27 to November 9, and laid them out hour by hour in Austin time. That came to 903 of them, about 65 a day. The orange bar on each night in the chart is the longest stretch he went without touching X. The median was 6 hours and 28 minutes. On a typical night, that was the longest he stayed off X, from his last post to his first one back. Some nights it was much shorter. Thursday November 5 into Friday, his last post went out at 3:34 a.m. and he was back at 6:46 a.m., a break of 3 hours and 12 minutes. Sunday November 8 into Monday, he stopped at 4:45 a.m. and was back at 8:18 a.m. Friday November 6 into Saturday, the longest break he took was 4 hours and 11 minutes. On 9 of the 13 nights his last post came after 1 a.m. The median time of that last post was 2:02 a.m. The median time he came back was 8:18 a.m., and on 12 of the 13 mornings he was already posting by 9:10. Only two nights went past 8 hours. The longest one, Sunday November 1, was a 12 hour break, and the next morning he was back before 8. And look at what he was posting while most of the country was asleep. At 2:25 a.m. on November 6 he wrote "Terafab is moving fast." At 3:32 a.m. he shared that "Starlink enables education in remote areas." A few hours later that same morning he announced that SpaceX will attempt to catch both the Super Heavy booster and Starship. At 1:20 a.m. on November 9 he was explaining that the Cybertruck order rate far exceeds production. None of this should surprise anyone who has listened to him. On Joe Rogan's show in February 2021 he said he normally works until 1 or 2 in the morning. When Rogan asked how much he sleeps, Elon Musk answered "About six hours," and said that when he tried sleeping less, his total productivity went down. Five years later the timestamps tell the same story. Back on X around 8 a.m., still on it around 2 a.m. This morning his first post went out at 3:13 a.m. Austin time, after a break of 5 hours and 43 minutes.
