Actually, a micropayment of a few satoshi could be viewed as some sort of proof of work.
So, no, as far as I know, Chat GPT doesn't own any corn.
Are you kidding, mate? It won't have bitcoin as of today, but what do you think prevents the AI of the future, say ChatGPT10 from making a bitcoin payment?
The problem as I see it is that today it already does many tasks much better than humans and in less time. Add to that the fact that we are in the early stages of AI, something like the internet in 1990, and it is expected to improve exponentially. Although I see this as positive in principle, I would not be blindly confident that there are no risks.
