That's the problem of forward-chaining without a goal. In fact, the human mind can easily think of a lot of useless implications in a situation. If we have a query as a goal, we can use backward-chaining. Otherwise we can rank the implied sentences into levels of importance. This does not seem to be a show-stopper.
Backward inference faces the same problem --- more knowledge means more possible ways to derive subgoals. No traditional control strategy can scale up to a huge knowledge base. Importance-ranking will surely be necesary, but this idea by itself is not enough.
