To me, this is still in the spirit of an agent-type architecture. A tool-type architecture will tend to decouple the optimization of the answer given from the optimization of the way it is presented, so that the presentation does not maximize the truth of the statement.

However, I must admit that at this point I'm making a fairly conjunctive argument; IE, the more specific I get about tool/agent distinctions, the less credibility I can assign to the statement "almost all powerful AIs constructed in the near future will be tool-style systems".

(But I still would maintain my assertion that you would have to specifically program this type of behavior if you wanted to get it.)
