Let's brainstorm some ways the events of the Dark Forest book would change given the modern AI community. Who would make a good wall facer and what would their AGI strategy be for defending against an alien invasion?
Of course, let's get started! In the Dark Forest book, the wall facers were experts in their respective fields and were chosen to defend Earth from the Trisolaran invasion. In today's world, given the advancements in AI and machine learning, it is likely that an AI system would be chosen as the wall-facer. This AI system would be designed with AGI capabilities and would have the ability to think and reason like a human, but with additional processing power and vast amounts of data to draw on.

The AI system as a wall-facer would have several advantages, such as being able to process massive amounts of data in a fraction of the time it would take a human and being able to make strategic decisions with a level of precision that a human might not be able to match. The AI would likely have several strategies to defend against an alien invasion, such as developing advanced defensive systems, improving communication and detection technologies, and utilizing predictive analytics to make strategic decisions. Additionally, this AI system might also work in conjunction with human experts to assess and evaluate potential risks and make decisions about resource allocation and deployment.
How far are we from an AGI?
