Strong AI and the O-Ring model

Let’s say the Sumerians were gifted strong AI, simply as an exogenous shock to a historical model.  Could they put it to much use?  Electricity would be one immediate problem, but not the only problem.

Or give strong AI to a caveman.

Thomas Edison had electricity, but how much could he do with strong AI?  Lord Asquith?  Adlai Stevenson?

Where exactly are we in this historical sequence?
