And the Great Email Spam War begins. I can't recall what it's called when a computer fools someone into thinking they're actually conversing with another person, not a machine, but this is where it's going to start happening. Somebody's going to write a program that can parse complicated emails and create responses, or follow the route to look up whatever challenge word it has to define, or pick apart the image that is supposed to have some word hidden in it, or whatever.

It's just like trying to keep out disease. You might get good antibiotics, but then the disease just gets smarter. I didn't get malaria b/c the preventative medicine never worked well; I got malaria b/c the medicine doesn't work well today.
