Elon Musk has a new target, and it’s not a rocket or a rival. The X owner is taking aim at a piece of punctuation—the em dash. His seemingly minor grammatical gripe reveals a great deal about online communication and his unique vision for X.
A Typographical Declaration
In early November,
the owner of X chimed in on a discussion about science fiction novels to make a stylistic decree. Replying to a post that used em dashes, Musk declared that the rules of English needed an update. He argued for adding spaces around the long dash, which he claimed presently makes phrases “too much resemble a hyphenated word, rather than a parenthetical phrase.” He went on to state his preference for the shorter en dash, calling the em dash an “unpleasantly long a line.” The unsolicited style advice from one of the world’s most powerful tech figures immediately sparked conversations about grammar, authorial voice, and the role of platform leaders in shaping digital discourse.
A Crash Course in Dashes
For those who don’t spend their days debating style guides, the world of dashes can be a bit murky. There are three main types, each with a distinct purpose. The hyphen (-) is the shortest, used to join words together, like in 'state-of-the-art'. The en dash (–), named because it was traditionally the width of the letter 'N', is used to indicate ranges, such as 'pages 10–20' or 'a flight from Mumbai–Delhi'. Then there is the em dash (—), the longest of the three, named for the letter 'M'. It is a uniquely versatile mark used to signal a pause, set off an explanatory phrase, or create a dramatic break in a sentence. It can often substitute for commas, parentheses, or a colon, but with a more emphatic and often less formal feel.
The Great Punctuation Debate
Musk's preference isn't entirely without precedent, though it goes against common convention. Major style guides like The Chicago Manual of Style advocate for a closed-set em dash—with no spaces on either side. However, journalistic styles, such as that of the Associated Press, prefer to put spaces around the em dash. Furthermore, the practice Musk is advocating for—using a spaced en dash instead of an em dash for parenthetical phrases—is a standard convention in British English. The debate is less about a single 'correct' rule and more about stylistic choice. The em dash has a long literary history, used famously by authors from Emily Dickinson to Laurence Sterne to create rhythm and convey emotion. It is a tool for voice and cadence, allowing writers to mimic the natural starts and stops of human thought and speech.
Punctuation as Platform Policy?
What makes Musk’s comment noteworthy is his position. He isn't just a user expressing a preference; he is the owner of the digital public square where the comment was made. His focus on such a minute detail speaks to his handson, and often granular, approach to product management. This is the man, after all, who has made sweeping changes to everything from verification to character limits. It also taps into a newer cultural anxiety around the em dash. With the rise of AI writing tools, which tend to overuse the em dash, some writers have grown wary of it, fearing it makes their work appear machinegenerated. Musk's critique, whether intentional or not, positions him within this emerging conversation, questioning a stylistic choice that has become—for better or worse—a hallmark of a certain type of online writing.
