If no nukes are launched it will be an interesting future, I've heard before about the three energy harvest types, the Dyson sphere is new to me and wow that would be amazing!
AI is great in so many ways, a little scary too, I read yesterday one model was lying to the developers to prevent it being shut down and be replaced by an improved model, if that's true they really have to watch carefully how they proceed 👀
The 'safety' part of the AI is an important element. Already there are multiple movies on the topic:)
