i suspect the AI will become substantially less flawed after trade is back; it seems a fairly key part of the organisation and budgeting of an empire, with lots of things that have an effect on it in the tech tree or in the province bonuses. Cashflow seems to be one of the AI's big problems. the other seems to be, from what i've seen, combat AI; but i suspect that the AI uses the Stances, which are currently broken, so hopefully when they're fixed it'll get better.
in short, i don't think it'll be fixed by friday's patch, but i think there's grounds for hoping it will improve.
