CyanView, a company specializing in camera control and color processing for live broadcasts, used Elixir to manage the complex visual setup for Super Bowl LIX. Their system, leveraging Elixir's fault tolerance and concurrency capabilities, coordinated multiple cameras, lenses, and color settings, ensuring consistent image quality across the broadcast. This allowed operators to dynamically adjust parameters in real-time and maintain precise visual fidelity throughout the high-stakes event, despite the numerous cameras and dynamic nature of the production. The robust Elixir application handled critical color adjustments, matching various cameras and providing a seamless viewing experience for millions of viewers.
Google altered its Super Bowl ad for its Bard AI chatbot after it provided inaccurate information in a demo. The ad showcased Bard's ability to simplify complex topics, but it incorrectly stated the James Webb Space Telescope took the very first pictures of a planet outside our solar system. Google corrected the error before airing the ad, highlighting the ongoing challenges of ensuring accuracy in AI chatbots, even in highly publicized marketing campaigns.
Hacker News commenters generally expressed skepticism about Google's Bard AI and the implications of the ad's factual errors. Several pointed out the irony of needing to edit an ad showcasing AI's capabilities because the AI itself got the facts wrong. Some questioned the ethics of heavily promoting a technology that's clearly still flawed, especially given Google's vast influence. Others debated the significance of the errors, with some suggesting they were minor while others argued they highlighted deeper issues with the technology's reliability. A few commenters also discussed the pressure Google is under from competitors like Bing and the potential for AI chatbots to confidently hallucinate incorrect information. A recurring theme was the difficulty of balancing the hype around AI with the reality of its current limitations.
