Sure. But that's a very common situation. Computers are very good in many computational aspects, but still human insight is needed to break a problem up into sub-problems of chewable size, or transform the original problem into one that is more accessible to automatic solutions. And even if a computer algebra system (no matter which one) gives an answer to a problem, one should never blindly trust it. One should always use one's mind.
