Elon Musk took aim at the growing use of pronouns in discussions surrounding gender identity this week, arguing that the practice represents an unnecessary development in modern language.

“It's the dumbest thing ever,” Musk wrote when discussing pronouns. He added that whoever came up with the concept deserves a “punch in the face.”

Musk has repeatedly criticized efforts by companies, schools, and other institutions to encourage people to identify their preferred pronouns. He has argued that individuals should not be pressured to use language that conflicts with their understanding of biological sex.

The comments are part of Musk’s broader opposition to what he has described as ideological changes in language and workplace culture. He has previously criticized corporate diversity and gender-related initiatives, particularly when they involve requirements or expectations placed on employees.

Musk’s comments add to his longstanding criticism of gender-related policies and language, a subject he has frequently addressed while arguing that cultural and workplace institutions have moved too far toward enforcing preferred terminology.
