On being commanded to roast Elon Musk with one word, Grok called the billionaire "overrated". Musk called Grok's response "accurate". Reacting to this, an X user said, "Love Elon's humour." Another joked, "And this was the last thing Grok said before being formatted." Notably, Grok is an artificial intelligence (AI) chatbot which was recently launched by Musk's startup xAI.
