I Am Teaching My First Grader to Code and You Should Too

I've played Robot Turtles (http://www.robotturtles.com/) with my 5 year old at a friends place and they all appeared to enjoy it. I'm not sold on whether it's teaching "programming" any more than any sequence toy/game does...
I've used Scratch, through volunteering in the engineering department at my local science museum. It's okay, although I'm not convinced it will turn 6 year olds into brilliant programmers later in life, any more than "creating things" in any other context would.
I don't know. I'm divided. Sentiments like "I'm teaching my <very young child> to code and you should too" leave a bad taste in my mouth, though.
