show's good. sonoya mizuno was the best part of maniac, so i'm excited to see what she does in this.

i'm getting the sense that nick offerman is trying to create a 'golden path', a la dune. devs' thesis on determinism seems to be that if you forecast backwards to unpack and analyse all the various causes of past events, you can create a model that predicts future ones. which is of course wrong, but it's a fun idea so whatever.

If you have a machine that can extrapolate particles' previous states from their current action and state you can already 'see' both forwards and backwards. It's not about creating a model that predicts the future, their machine already can see the future. This also makes it one of the most implausible sci-fi shows ever.

If people wish to read more on the topic, it's basically this: Laplace's demon.

My unspeakably lame guess for the final episode, to be made fun of in due course when I am horribly wrong:

Lily shoots the Devs computer and ends existence, hence not being able to view past that point. The universe is simulated by Devs, which is contained within the universe it's simulating. "The box contains everything" i.e. including itself.

This is really not bad! My guess is similar, but that the events taking place in Devs are just the simulation (our universe, one of infinite simulations) running its course/requiring too much energy to keep going before it is terminated. Simulated by aliens, future humans, god, or otherwise.

Yeah but the blurry stuff had no sounds. They only got the sound to work when they did multiverse. It really looks to me like Forest and Katie have something figured out the rest of the team doesn't.

Blurry stuff definitely had sounds! They just got fuzzier along with the visual data the further you went back.

From what they've shown on the show so far, both the Everett interpretation (many worlds) and the de Broglie–Bohm interpretation (one world governed by hidden non-local variables) are correct/compatible with each other.

The Deus computer has limited computational capacity and is unable to model everything using de Broglie-Bohm (their computer would need to model every single quantum bit). The Everett interpretation somehow allows them to use a more limited set of data to create a much clearer, for our purposes random projection - the results can be very close to the world they're in, or very different since the computer is just guessing instead of calculating precisely what state particles are in - and each time they run the simulation will inevitably be different.

A goon earlier in the thread mentioned that the show hasn't dealt with compatibilism, the idea that a deterministic universe and free will are compatible. At this point, I'm almost inclined to think that's intentional. Forest has his determinism thing — the "rails" — and is literally building a god machine to figure it out, but 5 minutes on Google would complicate that simple, binary, either/or answer he's going for. It would also complicate any of his and Katie's over-confident justifications for literal murder. As Stewart says, the dude can't even guess. He's just not interested. Both Katie and Forest, despite their intelligence, are pretty much Dunning-Kruger incarnate.

Thankfully the show isn't even considering compatibilism because it's a horse-poo poo idea.

So is Katie lying when she says she believes that Many Worlds is the correct interpretation? Either way the Devs system seems to prove that Many Worlds is the truth of their reality anyway, so what Katie says to Lyndon is at least partially true; his consciousness continues to persist in the universes where he survives the experiment, or in the universes where he chooses not to climb over the rail at all, but those all deviate from the universe that the Devs system is simulating, because it is somehow *both* deterministic and multiversal. So as far as this iteration of Katie is concerned, Lyndon had no other outcome but death.

Many worlds is strictly deterministic because it isn't random, and it doesn't literally mean "everything can happen". It's possible there are zero universes in which a Lyndon survives.

Since they have used the machine, it is the observer, and therefore collapsed the possible outcomes into a single result causing the deterministic outcome in the future.

also, if you do not watch PBS Space Time on youtube (https://www.youtube.com/channel/UC7_gcs09iThXybpVgjHZ_7g), shame on you! And enjoy the episode on quantum eraser!

While this sounds cool, it doesn't make sense for the story when the machine is also producing many-worlds predictions. Eitherway you cook it, the show doesn't agree with the tenets of the Copenhagen interpretation.

Show was pretty but stupid the whole way through. Basically just a highbrow version of Westworld. Could done without that creepy six-storey doll though.

I also didn't appreciate the lazy "you tech bros are all just playing god" criticisms that kept being voiced, when the series showed off a more pertinent criticism. Why the hell was Forest such a passive sadsack despite the massive power he had? Isn't that like the billionaires who spend their time in bunkers asking psychiatrists how to prevent mutinies, because they're unable to imagine their power just addressing climate change?

Show went a lot further than something like Westworld in tackling its own philosophical themes, and it should be applauded for tackling one of the most difficult concepts in both science and philosophy, it just spectacularly dropped the ball at the end and decided to go "No, humans do actually have agency beyond the confines of the material world (a soul or whatever)", and that either Lily has such a powerful soul that she can materially affect her own decisions, or that the others were content in letting determinism guide them and all humans in the end have the kind of agency/choice that makes decisions truly their own.

It's a very dumb ending for a very thoughtful show - but quite a good ride anyway.

Isn't the point that it's a matter of perspective? It's not that there could be zero universes in which Lyndon survives, it's that there could be zero universes in which Lyndon survives from Katie's perspective as she continues along one of her own paths. From Lyndon's perspective, he may have stepped back from the brink, seen Katie get hit by a bus, and continued life some other way that we're not shown because it's not his timeline we're following, it's some variation of Katie's or someone else's.

The worlds where Katie is hit by a bus are so drastically different that we can safely discount them, same as worlds where for whatever reason Lyndon never applied to Amaya and still lives.

What I meant was if you make Lyndon stepping on the edge of the dam your starting point, and consider that the many (not infinite) configurations of particles in the air and in his body are what will determine whether he lives or not, it's possible that from that starting position, all configurations lead to him falling. The possibility space in many worlds is not infinite.

I think there's a way to interpret Lily's actions as deterministic and paradox causing. Deus was predicting that Lily would watch the simulation of her final moments and adjust her behavior as a result.

If Lily watches herself shoot Forest, she 'chooses' to defy the simulation by throwing the gun out of the lift.
Therefore, Deus has to predict that Lily throws the gun out of the lift. But when Lily sees that she throws the gun out of lift, she 'chooses' to defy the simulation by keeping the gun and ends up using it.

And then Deus just has to loop this forever which even with near infinite processing power causes the system to fail. Lily isn't displaying freewill. Determinism dictates that Lily always defies the simulation which creates a paradox that overwhelms the simulation.

User A seeing the future in a deterministic world wouldn't give you a paradox because that future was always predicated on User A seeing it. It's only a paradox because our minds can't square determinism with our conception of free will.

Write out how Lily observes a film of her watching the simulation and then contradicting the simulations prediction.

Lily can't contradict the simulation except as follows:

- Lily has a soul that isn't affected by causality or the laws of the universe, this soul object can magically affect the way she interacts with the universe around her.
- The simulation is imperfect for whatever reason (lack of data on all sub-atomic particles / universal laws not accounted for) and as such gives off wrong predictions.
- The universe is actually truly random as posited by the Copenhagen interpretation and the random prediction seen by Lily was useless.
- All possible outcomes of subatomic particle interaction are realized in a world (many worlds), Lily just happened to see a divergent future prediction.

Show picked that first one.

To try and see it from another angle, replace Lily with a computer. If the computer sees its code running 5 seconds ahead, it will interpret the code in a very specific manner according to its design and software that will inevitably lead to running that exact code 5 seconds later. The computer has no choice in the matter.

The universe is still deterministic, it's just that Forrest is completely wrong and Deus doesn't accurately predict it, because it can't account for people changing their mind based on the machine's predictions, because it sends it into an infinite loop. Lily didn't violate any laws of nature or determinism, she just found a fault in the machine.

But there is no infinite loop involved since the machine is capable of simulating itself over and over again as seen with Stewart and the other devs 2 episodes prior.

The machine doesn't make false predictions because it also factors in Lily seeing the outcome on the machine and acting based on that. For all intents and purposes the machine seems to have infinite power and is fine simulating a simulation within the simulation to reach the inevitable outcome.

There aren't multiple frames of reference where Lily either sees the outcome or doesn't, Lily always sees the machine and always acts a certain way in response.

That explanation is also against the entire message of the show unless that message is "the universe is completely deterministic and you don't have free will but at least you can't predict it".

If you go in with the intention of not doing what it shows you, it can't show you what you are actually going to do. If it shows you flipping the bird, and then after seeing that, you decide you'll put your hand in your pocket, the machine can't go back in time and actually show you putting your hand in your pocket. It can't take everything into account if you decide not to follow its calculation. There's no way for it to show you what it calculates will happen and then for you to think you're doing the opposite but actually doing what it predicted.

Particles don't have a choice about their interactions based on stimuli, what you're proposing is literally magic or randomness.

It's funny but randomness is actually the mainstream interpretation of quantum mechanics which the show completely ignores.

A deterministic universe is contrary to our perception of reality, but that doesn't actually mean it has to be wrong.

This isn't entirely true, it's just contrary to our conception of self. Our perception of reality quite easily accepts that event A causes event B, it's just unintuitive to apply that to ourselves as well as the world around us so people rarely do so.
