Thus no need for monster AI programs to cope with all possible contingencies - humans are ready made for that purpose. The model to think of is a sophisticated computer game. The trade off here is decreased reliance on sophisticated AI programs that we all concede that state of the art is not capable of producing and increased reliance on software that provides an excellent interface to the human operator. Of course, this increases the problems associated with real time secure communications, but you were going to have to face them anyway. But this might be easier to manage than most.
Meteors are just a casual example.
That is absurd on the face of it. I think the approach has merit, particularly over a monolithic system, and should not be shot down out of hand. This corellation could come about as a result of proximity, similar hardware or software, or a general design likeness. The effect would be to increase the probability that the overall decision is correct. Most of the points he has raised need careful consideration.
