This is a man standing too close to the forest to see the trees. He's right, but also completely wrong.
What is being taught is "computational thinking", not coding. Coding is just the conduit.
It's a skill that has application far beyond the keyboard. It's not about learning the syntax of a for-loop, it's about the epiphany that follows. Seeing a kids face when they (all too rarely) get it that they've become wizards and the sky is the limit, is priceless. They are visibly empowered and their view of their relationship with the world around them alters.
*That's* what it's about.
