On September 18, as per The Wall Street Journal, individuals with insider knowledge of the situation disclosed that a number of xAI executives have stepped down. This exodus was prompted by clashes with two of Musk's closest confidants, with underlying worries about the company's management approach and financial well - being. At present, the day - to - day running of xAI is entrusted to Musk's trusted aides, Jared Birchall and John Herring, while Musk himself holds the reins for final decision - making.

In the past few months, a slew of xAI executives have left their posts. Among them are the former CEO, Linda Yaccarino; the ex - CFO, Mike Libertore; the General Counsel, Robert Gill; and the co - founder, Igor Babuschkin.

Explanation: 1. “Reportedly” is replaced with “Allegedly” which is a bit more formal and often used in news - related contexts when information is not fully confirmed. 2. “Confidants” is kept but the description around it is made more natural. “Trusted aides” is also a good alternative that conveys a similar meaning in a more common English expression. 3. “Sparking Conflicts” is changed to “Triggering Clashes”. “Trigger” is a more vivid verb, and “clashes” is a more commonly used term in business - related conflict descriptions compared to “conflicts”. 4. “Leading to Resignations of Several Executives” is rephrased as “Prompting Resignations of Multiple Top - Brass”. “Prompt” gives a sense of a more direct cause - and - effect, and “top - brass” is a colloquial but well - known term for high - level executives. 5. In the second paragraph, “driven by concerns” is reworded to “with underlying worries” to make the sentence flow better and sound more natural in English. 6. “multiple” is used instead of “several” in the first paragraph and kept in the second paragraph for consistency, and it also has a slightly stronger connotation of a relatively large number. 7. The list of executives is presented in a more streamlined way with semicolons to separate the items, which is a common and clear way to list multiple elements in English writing.
