Later that “day” in hyper-dimensional space, Billy bumped into Laplace’s Daemon, who was looking dejected.
“Hey, LD, what’s up?” Billy asked, cheerfully.
“Oh, hi Billy,” the daemon rumbled. His voice, almost subsonic, sounded hollow. “I’m feeling a bit low, to tell the truth.”
“Cheer up LD, what’s wrong?”
“I feel pretty useless, Billy.”
“Oh come on.”
“I’m not good at anything…”
“That’s nonsense LD! You know the position and velocity of every particle in the universe! That’s pretty awesome!”
“I thought so too, but now I don’t know…”
“I failed to predict the outcome of the US presidential election…”
“Oh, bummer…but you’ve predicted a lot of other stuff correctly, right?”
“Well, not as such, no…”
“But…I thought prediction was your whole thing LD?”
“So did I…but I’ve never actually tried to predict anything before now.”
“Wow – isn’t that what you were created for?”
“I guess not. I guess I was created as an intuition pump like some smart arse philosophers have claimed…oh man, this sucks – I was so determined to try,” the daemon let out an almighty sigh. “Ha! ‘Determined’!” he suddenly shouted, slapping his daemonic thigh ironically.
“What’s an intuition pump LD?” chirped Billy, his ears ringing. He’d missed the joke but was always excited to learn new things.
“It means I was created just to convince people that prediction was possible in principle. You know, to show people how obvious and logical determinism is and how incoherent the idea that puny creatures like them could have ‘Free Will’ is,” the daemon made little bunny ears with his daemonic fingers as he pronounced the words “Free Will”, “…but I never really thought to test my powers.” He paused, shaking his daemonic head, “I mean, it was so obvious!”
Suddenly, Tegmark’s Daemon appeared in a puff of mathematics.
“Hi TD!” chirped Billy, whose irrepressible chirping was starting to get on the daemonic nerves of Laplace’s Daemon.
“Hi Billy! Hi LD – I hear you’ve had a spot of bother bit of predicting the future old chap,” said the newcomer.
“Bloody hell,” growled the older daemon, “everybody knows… I’ll be a laughing stock at the next meeting of the Council of Daemons.”
“Cheer up mate,” replied TD, trying to console his friend, “it’s not your fault. You just don’t know anything about quantum indeterminacy, that’s all.”
“What’s that?” asked LD, without enthusiasm.
“Would you like me to show you?”
“Yes!” exclaimed Billy, who knew it was rude to interrupt when daemons were talking to each other but was unable to contain his excitement.
“Excellent!” said Tegmark’s Daemon, ruffling Billy’s hair affectionately before opening his daemonic mouth and spewing forth a huge jumble of equations. While he explained them to his eager young student, Laplace’s Daemon picked his daemonic teeth disinterestedly with his daemonic claws.
Some “time” later, when Tegmark’s Daemon had finished his daemonic explanation, he turned to his fellow daemon and said, “So now you know, LD – it’s a bit harder to predict the future than you thought, because you have to analyse all possible universes and work out which one you’re in! You couldn’t possibly have known…”
“Whatever,” grunted the downcast daemon, brusquely interrupting his younger colleague.
Tegmark’s Daemon shrugged his daemonic shoulders, “OK chaps, I’m off then,” he said, and promptly disappeared in another puff of mathematics.
“Fucking precocious upstart,” muttered Laplace’s Daemon, alone with Billy once more.
“I feel bad for you LD,” said Billy, “but you have to admit, that was pretty cool!” The boy was beaming in the afterglow of the brief encounter with his favourite daemon – Tegmark’s.
“Piss off, kid.”
“Aw, don’t be sore LD. What are you going to do now?”
“I don’t know…probably start a psychic hotline.”
