This article looks back at three tech products that were really hyped up in 2024 but didn't do well: Apple's Vision Pro headset, Humane's Ai Pin, and Rabbit's R1 AI assistant. All three products had problems at launch, like not working well, being too expensive, or having privacy issues. Even though they got better with updates, they're still not very popular. The author tried using all three products again and found some improvements, but still thinks they're not worth the money or effort. The article also talks about how OpenAI, the company behind the popular ChatGPT, is changing its structure to become a for-profit company so it can raise more money to compete in the growing AI industry. This has caused some controversy, with people like Elon Musk trying to stop the change. Overall, the article highlights how difficult it is to create successful AI products and how the AI industry is changing rapidly.
