Couple of hundred billion brain cells in your skull.
You got more synapses than stars in the universe.
You are a fancy hand terminal.
Holden: Thanks
M: With a lot of buttons.
Now, I push a few trillion of them buttons in exactly the right way and, ta-da.
You’re talking to Miller.
The sound of his voice, the clothes he wore.
H: Plus the hat.
M: Yeah, I like the hat.
Plus, uh,
I’m pushing the buttons.
H: So it´s a magic trick.
M: So is your whole damn reality, kid.
Just different buttons being pushed.
H: Maybe I’m the illusion inside your head.
M: Whoa- whoa. Whoa.
I’m trying to keep things simple here for you, okay?
Pointing to himself: “Calculus.” Pointing to Holden: “Amoeba.”
Then, the reverse: “Monkey. Mozart.”
