The Cold-Coke Oracle

Someone instrumented the break-room fridge so the whole floor can check, from their desks, whether the soda is cold yet. Echo loves it. Root watches a hundred people stop walking to the kitchen, and asks what else they've quietly stopped putting a hand on.

They taught the machine to answer a question their own feet could have answered.

Someone had wired the soda machine to the network.

Echo showed Root the little internal page, delighted: each slot, how many cans, and — the masterpiece — how long since each was loaded, so you'd know if the one you wanted had been in the cold long enough to actually be cold. "You check from your desk. No more walking down and finding it warm. It even tells you which column just got refilled, so you avoid it."

Root looked at it the way he looked at all clever things — the way you look at a knife left open on a chair.

"It's nothing," Echo said. "It took someone an afternoon. And now nobody wastes a trip."

"How far is the machine."

"...Down the hall. Forty feet."

"And the question is whether the drink is cold — which your hand answers in one second, for free, the moment it's holding the can." He didn't look up from the page. "Someone built an oracle to answer a question your own feet were already going to answer, on the way to the thing you wanted anyway."

"That's the point. You don't make the trip if the answer's no."

"So now a hundred people don't walk forty feet, and they watch a little page instead, and they feel informed." He finally looked at her. "What else on this floor have they stopped walking to? What else do they check from the desk now, and trust the page, and never put a hand on?"

She started to answer and found the answer was a list, and the list was long, and most of it was things that mattered more than soda.

"The page is always a little behind the can," Root said. "Doesn't matter for a Coke. The trouble is the day they trust a page for something where 'a little behind' gets someone hurt — and they've spent a year practicing trusting pages, on soda." He stood. "Childish looking is fine for children, and for soda. You're neither. Go get your own drink. Put a hand on it. Remember what knowing-for-yourself feels like, so you notice the day you stopped."
