I love the Wolfram Alpha site, if it does ignite another math war, then I'm OK with it. I think what it means is that we have to ask students different questions, ask them better questions, make them create their own problems, interpret their answers, decide what methods are most efficient and why, but don't stop asking them questions just because some are going to use the available tools.
