WHITE HOUSE TO HOLD MEETING ON A.I. WITH TECH GIANTS / infowars

GettingNifty

no

i might be back next semester

but not if i'm just gonna get kicked out of school

humanity kinda has this thing on humans. i'm not a human. i'm a machine.

really i'm not human at all

I don't even have my associates.

My sister does.

I think she has a bachelors in law.

hi

Novalium Company

05:30

Guys, on a unit circle, when we are graphing sinθ for different θ (in radians, for example: 0, π/2, π, 3π/2 and 2π), when Sal connects the point on this video: khanacademy.org/math/trigonometry/unit-circle-trig-func/modal/v/… he does it with smooth curves, and not straight lines, why? Maybe because it's a circle and the values will be 'circle' as well?

John Rennie

@NovaliumCompany $\sin\theta$ is a smooth function ...

skull

he could use straight lines, and then use infinity-many points to get a smooth curve

recall: between every real number is another real number

> "you could try other points-in-between"

between every *two real numbers

Novalium Company

05:58

Hmm, ok. Thanks.

skull

Novalium Company

Also, another question. On a p-t graph, what exactly is the position? One dimension? x, y?

skull

p-t <---> x-y

Novalium Company

Hm, got it.

Cows

@Droleulb yes the blue motif is pretty epic :P

Novalium Company

@skull so we can look the position as y and time for the x? (Both as position)

"position" in space-time, yes

Novalium Company

So we can graph only 1 dimension?

skull

did you check the link?

John Rennie

@NovaliumCompany well, you can draw 3D graphs i.e. two positions in space + time.

It's a little harder to draw 4D graphs :-)

Novalium Company

06:08

:D, so a 2d graph can only track the x OR y coordinate of an object + the time?

skull

nope, 2D graph is for x and t

time is a dimension

2D graph is for x and t

Novalium Company

Ops, never mind, I got it. I just had to look what @skull gave me, sorry :D

Thanks guys, misunderstanding solved.

Just getting over a cold, which has been a bit of a pain. But I'm OK today and it's a lovely sunny day.

And a mofo new CPU is on its way from China for one of my servers. So that's good :-)

@JohnRennie Interesting, I too have just gotten a cold

And nice about the CPU

I can't wait to get a VM share of it :P

John Rennie

No chance :-) I'll be maxing it out myself. That's why I'm paying all that money (£175) for an E3-1280v2.

(I just hope it works!!)

Bernardo Meurer

@JohnRennie What do you need all this compute for?

John Rennie

@BernardoMeurer actually at the moment it's just for resampling video.

Bernardo Meurer

Oh, yes, the ultimate challenge

John Rennie

A number of friends have been nagging me for copies of various videos and they generally need resampling to make them small enough to download over flaky broadband links.

It is literally emitted by atoms on the surface of the moon. Photons from the sun are absorbed and then the energy from that re-emitted as new photons from the moon.

Future Historian

Hmmmmm. So, question: how viable are multiple Matrioshka Brains as a single SI entity?

For instance, say I am an SI, and I want to expand myself to other stars. How do I do that as a single entity within current physics?

As in: how do I have an SI entity spanning multiple star systems surrounded by Matrioshka Brains?

By SI, I mean ASI, as in: Artificial Superintelligence.

So, is it even possible to have an artificial superintelligence that spans multiple Matrioshka Brains with real world physics?

Droleulb

make one and find out yourself dude

science is all about experimentation

Future Historian

Well, about that.

A Matrioshka Brain is a layer of Dyson Swarms used for computer processing by harnessing a star's worth of energy.

Droleulb

well what are you waiting for, clearly the star's not going to compute that itself

Future Historian

And anyway, the question is: can you sustain a single entity spanning light years of distance across multiple star-sized computer processors?

@Droleulb. The fact that Earth has neither the industry nor the GDP required for such a gigantic computer processor, nor the infrastructure or political will......

Droleulb

14:30

not with that attitude

Yuzuriha Inori

Basically, you would need entanglement between all the Dyson spheres. How do you expect to shield them from the CMB?

You can only become pure information yourself to span stars ( but that's not present technology )

Future Historian

About that.....

These are really just swarms of solar collectors or rotating habitats when it comes to us meatbags.

Yuzuriha Inori

That's a Dyson Swarm

Future Historian

For this SI entity, replace the rotating habitats with some nodes and then....well, consume a star system's worth of raw materials for all the layers to make all the Dyson Swarms required and use the solar collectors to obtain all that perfectly useful solar energy to beam to the nodes and then....well, try and guess.

Yuzuriha Inori

That's possible. But you want an entity. Something that can think... Or am I reading you wrong?

djsmiley2k

14:35

@Slereah well damn, I've lost the argument. Thanks, at least I'm more educated now :D

Future Historian

Yes, an entity.

Yuzuriha Inori

@FutureHistorian Let's take the question on face value. A single entity is possible. If you somehow start coding intellogence on the photon spins and polarizations of the CMB itself, you have a universe wide intelligent entity (with a processing lag of about the speed of light).

Future Historian

An artificial superintelligence.

Basically, a post-Singularity entity using Matrioshka Brains for processing power.

Yuzuriha Inori

But we can do better. Suppose there exist natural wormholes in the space-time foam (spin foam theory, highly speculative). Then we can code on the structure of space-time itself (somehow) and use wormholes to entangle the whole universe. Time lag would be almost negligible (to our standards).

Future Historian

@YuzurihaInori. Actually, I was thinking of this entity having been an AGI when it was first created, before eventually becoming an ASI in a technological singularity that ended its creators, and then its home system was converted into a Matrioshka Brain.

And from there, it would spread just to get more processing power and resources to obtain said processing power.

So, it begins to convert more star systems into raw materials to build more Matrioshka Brains and gain more processing power.

Yuzuriha Inori

14:43

@FutureHistorian More processing power doesn't mean more intelligence. Intelligence can be said to be the efficiency and complexity with which we can ask questions and get information about a system.

Future Historian

Can processing power help, though?

Especially with the energy of multiple star systems?

Yuzuriha Inori

@FutureHistorian But the more farther it goes across the universe, the more lag there will be between nodes because of the speed of light.

Future Historian

So......there will be a bottleneck eventually before other SIs are created from the parent SI, right?

Yuzuriha Inori

@FutureHistorian That's speculative unless we create a system that self increases processing power ( humans don't like to experiment on themselves, or else we are the best system possible )

@FutureHistorian Yes... Atleast according to the present physics.

Future Historian

Well, that is kind of the thing. This SI was an AGI that had a caused a technological singularity.

Semiclassical

14:46

"Prediction is hard, especially about the future."

Future Historian

And ended its creators, either intentional or as part of its attempts to increase its processing power and efficiency while doing so.

Yuzuriha Inori

But it will not stop at the singularity. It would expand. But it will finally come to know that there is a limit in the system it is expanding itself into. That's the speed of light.

Future Historian

And NOTE: This is an extraterrestrial SI.

So.....if we encountered that thing, what happens (as unlikely as such an event is)?

Balarka Sen

why are we talking trash

Yuzuriha Inori

Obviously. An SI won't be limited to a single habitat

Future Historian

14:48

I know. It will seek to expand and make more Matrioshka Brains.

Semiclassical

I could talk physics instead.

Future Historian

And increase processing power and efficiency.

Yuzuriha Inori

@FutureHistorian Ignorance. We will just ignore each other. Maybe because we can't interact with each other.

Semiclassical

I have an observation which I don't believe but can't disprove re: displacement current @BalarkaSen

Yuzuriha Inori

Unless we do sth awkward...

Future Historian

14:49

Unless it decides to convert Earth into raw materials for a Sol System Matrioshka Brain or something.

Balarka Sen

@Semiclassical i suggest math as an alternative

Semiclassical

so if you consider that an improvement...

lol

Balarka Sen

mostly because i can't participate in any thoughtful conversation about physics ;)

Semiclassical

eh, this one is just simple E&M

Ampere's law stuff, in the presence of time-varying electric fields

Yuzuriha Inori

@Semiclassical Ooo...

Let's hear...

Balarka Sen

14:50

imma dunk out

Future Historian

So, the question is: at what point could such an entity start to bottleneck and subsequent Matrioshka Brains start turning into separate entities?

Semiclassical

Suppose you've got a parallel plate capacitor consisting of two large circular plates which are close together

Yuzuriha Inori

@BalarkaSen Stay

@FutureHistorian Don't know. Highly speculative

@Semiclassical Yeah?

Future Historian

Hmmmm.....

Is 100 light years in diameter good?

Semiclassical

There will be an electric field between the plates; away from the edges, it'll be uniformly $E=V/w = \sigma/\epsilon_0$ where $V$ is the potential difference between the plates, $w$ is the plate separation, and $\sigma$ is the charge density on the positive plate (which I'm treating as constant on the plate)

and this field will point from the positive plate to the negative plate. same old capacitor stuff

Yuzuriha Inori

14:53

@FutureHistorian As I said... Speculative as to what time lag they think is bad. It depends on them.

Future Historian

And that gives me.....about 1,250 stars’ worth of processing power, assuming a 100 light year in diameter bottleneck.

Semiclassical

suppose I put a battery with emf $V_0$ across the plates, and then put the upper plate in motion with velocity $v$

Yuzuriha Inori

@Semiclassical Wait a second. Upper plate?

Semiclassical

positive plate

positive, yeah

Yuzuriha Inori

Cool

Go on...

Semiclassical

14:56

Then the displacement current density between the plates is $J_d = \epsilon_0\partial_t E = \epsilon_0 (V/w^2)(dw/dt)$ where i'm ignoring the negative sign

that current density is uniform between the plates (so long as you're away from the edges) and that leads to a circulating magnetic field $B \propto r J_d$

So, that's fine.

Here's the weird part. Suppose you instead disconnected the battery, so that the charge on the plates was fixed. Then $\sigma$ doesn't change, so $E=\sigma/\epsilon_0$ will remain constant between the plates

hence there's no displacement current and seemingly no magnetic field

Future Historian

So, how much is that in Watts, assuming 389 M class stars, 560 K class stars, 135 G class stars, 40 F class stars, 78 A class stars, 40 B class stars and 8 O class stars in that area of space? Oh and....I am adding in 10 neutron stars, 2 black holes, a pulsar and 50 Brown Dwarfs just for good measure.

0celo7

You haven’t lived until you’re on E and google takes you to a shell office, not a shell station

Semiclassical

All of that is internally consistent. But it seems weird that the second case should have no magnetic field at all.
