Musk says “xAI was not built right” amid executive departures, Cursor hires
There’s been a lot of turnover lately at xAI, with numerous executive departures and, yesterday, news that the SpaceX-owned company was hiring two senior leaders from Cursor, an AI coding startup that’s raising funds at a $50 billion valuation.
The reason? “xAI was not built right first time around, so is being rebuilt from the foundations up,” CEO Elon Musk posted on xAI-owned X yesterday, in response to a post about the Cursor hires. Earlier this month, Musk told a conference audience, “Grok is currently behind on coding.”
The news amounts to an admission of a reset inside xAI and an acknowledgment that the company is trailing AI peers like Anthropic and OpenAI in one of AI’s most commercially important applications: coding.
xAI was not built right first time around, so is being rebuilt from the foundations up.

Same thing happened with Tesla.
