Because they shouldn’t be worth that tbh. They are a cash burning operation hoping to get what they can before the music stops.
Obviously it's not just students, but the fact it [numerically] could be is rather amusing and makes me surprised that it's only 1 billion active users, since GPT has a lock on name recognition amongst low information users.
I'm naive, but is this possible? The power required per user to run those GPUs seems like enough to run an air conditioner. For a billion people everyday or so seems like enough to overload power plants.
Not true. Maybe you're thinking of computer games? Inference requires much less energy per user session than a session of your average AAA game title. And there are more active gamers at any time than active ChatGPT users.
