hmmm, maybe they can manufacture more T-1000s

I was alerted to this story on National Geographic about a bendable concrete that heals itself with water. The substance is designed to make bridges and roads safer, and it sounds like a pretty nifty idea, but I'm just afraid the concrete will then start to develop a mind of its own, and then things are seriously going to go south from there. I mean, really, who needs buildings and roads that decide they aren't going to do what you want them to do, like, oh, I don't know, stand upright or lie there for you to drive over.
