"giant cable" -- this kind of thing does obviously happen, rural electrification is heavily subsidized by governments (see the rest of my comment..). But it is also not a realistic option in plenty of cases as such and therefore industrial companies like Cat and Cummins are happy to sell multi-million dollar generators. If your approach to the subject is to copy it into a chatbot it might explain why this discussion is ultimately specious, because a casual and even jocular approach to this is not really adequate to make any point.
