Wolfram Alpha, where were you when I was in school? Yesteryear’s calculator complaints are now seen as ludicrous and calculators are an integral part of our society. But I bet you will hear the same arguments in a few years when everyone is “showing their work” from Wolfram Alpha.
It’s actually a neat computational problem. It’s one thing to put some variables into a massive formula and get a single number, but to explain, step-by-step in words, what to do almost feels like artificial intelligence.
