How "AGI" could end up being many different specialized AI's stitched together

This is amazingly close to my thoughts on the subject, and you've said it way better than I could have. I have additional thoughts on how we can make the "manager" part of the system safer, although that is more potential implementation detail rather than what I expect to happen regardless of developers' views on safety.

I do agree that these kinds of systems are far more likely to be preferred both in the short term and probably the long term too, and that while they aren't without risk, reducing that risk would be an easier problem to solve than doing so for monolithic systems.
