To work out what subjects preoccupy Mr Musk and how his views have changed over time, The Economist analysed his activity on Twitter (as it was) and X (as it became in 2023). Using artificial intelligence to trawl through his 38,358 posts between December 2013 and November 2024, we found that he is posting far more often and with a far more political bent. Climate change and clean energy used to be the realm of policy on which he opined the most, but he now bangs on much more about immigration and free speech (see chart 1).It's safe to say that Elon Musk has the all-time worst case of Poster's Madness in the history of ever.
