Meh. If it works, it works. I think it works because it draws on bajillion of stories it has seen in its training data. Stories where what comes before guides what comes after. Good intentions -> good outcomes. Good character defeats bad character. And so on. (hopefully your prompts don't get it into Kafka territory)..

No matter what these companies publish, or how they market stuff, or how the hype machine mangles their messages, at the end of the day what works sticks around. And it is slowly replicated in other labs.
