I'm stereotyping and generalizing a bit, but the crowd I've seen adopting nosql and node and other "cutting edge tech" tend to be the same people who mock PHP for being crappy, invoking references to "register_globals"-style hacks as being one of many reasons why "PHP sucks!"

Is nosql going to (re)teach people that security is something you have to be vigilant of, regardless of the underlying tech? If so, good.
