There is already no shortage of investment and hype around their core product - but it definitely does not seem like something you'd want to cram into a physical product, and definitely definitely not something you'd need $1B to develop.
This smells like "Open"AI is on-ramping to the final stage, cashout.
1. Raise $1B for a device blessed with Ive cool-factor for maximum hype and sales
2. Launch this device for $999 ($1299?)
3. Record-breaking IPO shortly after
4. ???
5. Everyone realizes they don't really need a $1k device to tell them "As an AI language model, I can't answer that question" fifteen times per day
