Here's what I landed on.
When students write, their brains light up in every direction. The prefrontal cortex makes decisions. The hippocampus encodes memories. Broca's area translates thoughts into language. Multiple regions fire together, creating new neural pathways.
This is literal brain building. Every time a student struggles to find the right word, they're strengthening cognitive pathways they'll use for the rest of their lives.
And when they ask AI to write, those regions of the brain are far less engaged, or not involved at all.
I'm worried that students are skipping the process of discovering who they are as thinkers and writers. They're letting a machine's generic voice become their substitute voice before they've had a chance to develop their own.
I know my own writing voice, because I've had decades of practice refining my craft before AI was invented. I can tell when AI's suggestions are effective, accurate, and fit my style of communication (and when they don't.)
But our young people are still figuring out who they are. And if AI becomes their default, they might never find their unique voice.
That's the loftier reasoning, I suppose. But equally compelling to me is this:
Everyone wants to write with AI, but no one wants to read AI.
I want kids to dig into the reasons why this is true, and use that understanding to inform their own approach to artificial intelligence.
