Probably gonna show a lot of ignorance here, but isn’t that a big part of the difference between our brains and AI? That instead of one system, we are many systems that are kind of sewn together? I secretly think AGI will just be a bunch of different specialized AIs working together.
Efficient and effective organizations work this way, too: a CEO to plan in broad strokes, employees to implement that vision in specific ways, and managers to make sure their results match expectations.
