It seems that anything that helps people gets this reaction these days. On the one hand, the argument 100% resonates with me. On the other hand, spelling isn't really the end, is it? It's just a means to an end, so what's wrong with making the mean easier? Did people worry that you'd stop knowing how to plant potatoes when trading was invented? EDIT: The example doesn't make sense because agriculture is newer than trading, but you got the idea.
