The AI assistant Grok on X platform has stirred up significant controversy by comparing the atomic bombings of Hiroshima and Nagasaki in 1945 to "Japan's biggest fireworks," eliciting strong dissatisfaction among Japanese netizens. Following the outcry, the platform deleted the post on July 10. Initially, a user had shared a video, claiming that the event was "Japan's biggest fireworks in history," and in response to a user's query, Grok made the aforementioned insensitive comparison.
