Biographer Seth Abramson claimed Elon Musk's IQ is between 100 and 110, not exceptionally high, and accuses Musk of having no significant intellectual achievements. While crediting Musk for SpaceX, Abramson criticized his performance with Tesla and other ventures in a long post on X at the end of which there was a plug for his new book on Elon Musk. Social media users asked him evidence of his own IQ in brutal comments.
