I actually like the way the AI trades now, it really makes for a great challenge! 
However, i think the real issue is the difference in quality between early AI and late game AI. BAsically the early game AI is very good and the AI often storms into a 2-4 tech lead as it meets the other civs and trades the early starting techs.
However, about the late MIddle Ages onwards the human player always catches up... this is basically because the human player builds far more improvements both in and outside of their cities and more often than not can avoid advancement zapping wars to do this..
Other than that though i cannot see why the AI always starts slipping round this period. MY cities are always the most productive, even though i'm often maybe only the 2nd-4th in population/territory size.
So we need to find ways to improve late game AI, whether it be by tech trading or improving their cities?! I always seem to be able to monopolise the late game wonders too...maybe it's cause these are far more spread out tech wise, or that in general one can usually build them much quicker in a number of highly productive cities?!
Who knowS>!?
