Am I missing something?

Someone took issue with my TEDx talk (again).
Specifically where I make this heretical assertion:
“It’s a faulty metaphor, that the brain is a computer. It’s not.”
So he or she commented:
“This guy (me) needs to look into the definitions of some words, e.g. ‘computer’.”
And so I did.
And every definition I’ve found makes use of these words:
Machine, device, electronic, program, operations, mathematical, logical.
Nowhere did I come across animal, biological, impulsive, emotional, stories, illogical.
Am I missing something?
I don’t think so.
Last week, I was walking down the street with my philosophical attorney friend.
(Rare, I know).
It was a beautiful day and we had just finished a wonderfully rich conversation over lunch.
As our gazes wandered ahead of us, I called attention to the not-so-obvious.
“You know, you and I are not seeing the same thing right now.”
He didn’t bite.
“Of course we’re not. Perception is selective, subjective.”
“And,” he added, “You’re not seeing the same thing you were seeing the last time we met.
And I’m not referring to the blossoming flowers and trees.”
(Turnabout’s fair play).
“How’s that?” I bit.
“You were quite concerned about the future, and it was coloring your perceptions.
You seem more alive today, brimming with possibility.”
He was absolutely right.
The “data” being “input” into my mind was not only selective and subjective, but highly dependent.
On my mood, my present interests, my focus and desires.
As John Milton so dramatically expressed in Paradise Lost:
“The mind is its own place and in itself can make a heaven of hell, a hell of heaven…”
Doesn’t sound much like a computer to me.
