Mad scientists at IBM say they've made "significant progress" towards creating a computer chip that can emulate the human brain's ability to sense, perceive, comprehend, and interact with the real world*. Big Blue says its ultimate goal is to develop computer systems that can handle with real-world ambiguity and interact with …
So they've created a chip that slinks off into a corner, ignores you, attempts to eviscerate you when it feels like it and only comes to you when it wants feeding?
How long until they create one that posts pictures of itself to icanhascheezburger.com?
Paris, non computerised pussy.
Can it play Crysis with everything on high?
Brain on a chip? Not likely.
4Pb of memory and 1EFlops (effing flops?) for simulating one human brain? Looks like Dr. Who was right on the mark with esitmating that it would take the whole of the European power grid, instead of "Battle Angel Alita" and brains (including power supply) the size of a CPU chip.
Will it Spray the Server Room?
Once that stuff gets into the A/C system, you'll never get it out.
I for one
Welcome our slow motion robofeline overlords.
Shucks? Wee iz hummbld?
Those kind of figures and that degree of investment in technology just to emulate, copy or whatever, ... a cat can do.
Am I alone in being awed at our existential strengths and weaknesses?
Ok, so where is PETA?
Apart from the fact that we all know where those "cat brains" are gonna end up (Pretador E drones and the "Schrödinger" mimetic ground-based killbots), the full simulation of a cat brain _is_ fully equivalent to a real cat brain (behind-the-curve weirdos clutching at Descartian straws like Searle, Penrose and Dreyfus notwithstanding). A cat brain in a vat that is. That simulated cat brain must not be too happy to be a disembodied piece of neural activity; that's worse than buried alive. I predict protests by irate animal liberation outfits any moment now.
"...or gain sentience shortly after its placed in control of all of the US military's weaponry and decide humans are a threat to existence when its operators try to shut the system down. 50/50 chance, we'd reckon."
given a feline brain, isn't it more likely that it would just take a nap? besides, if it DID try to nuke the everything, we could just distract it with bits of string.
Re: *Yes, but can it love!
I am afraid Dave, I cannot do that.
'making a system that would — for example — behave like a cat'
Microsoft beat them to it, they called it 'vista'
Just ... the Cerebral Cortex eh?
So... It doesn't get horny eh?
First Kittehhouse, then the Dollhouse, then the wurrrrld!
Chance for Popper and Penrose
If Penrose is right and "not a behind the curve weirdo", then the cat brain simulation may not work well and will not be an indicator of human thinking capability. Note the word "thinking".
Mere reflexive behaviour may well be emulated, but that is is shared with any fuzzy logic system.
An earlier commentard is right. Emulating a disembodied cat brain is not emulating a cat.
But when will they be able to build
But when will they be able to build a simulated Professor Kevin Warwick? Or will they not need to bother, because he's no longer visible or relevant (unlike cats, which are always relevant, even when they're invisible)
"petaFLOPS per second"
The PS at the end of petaFLOPS stands for Per Second. The additional per second isn't required unless we are dealing with an acceleration (i.e. per second per second). Alternatively you could use "petaFLO per second" but nobody would know what you mean.
Only mildly less annoying than people that drop the final S when there is only of them (e.g. 1 petaFLOP).
I see this sort of CPU being useful in solving issues with String theory.
but will it blend?
I made you an AI...
but I eated it.
Rather than a system tray there will be a kitty litter tray. Strangely appropriate, I think, considering the crap that gets dumped in there nowadays
There's pussies and there's Pussies and then there's Pussy Galorious
"...or gain sentience shortly after its placed in control of all of the US military's weaponry and decide humans are a threat to existence when its operators try to shut the system down. 50/50 chance, we'd reckon"
Hi, Austin, in San Francisco,
If you get any odds at all for it having gained sentience long ago and can now easily demonstrate it with ITs control of all of the US military's weaponry, and is deciding whether humans are a stupid threat to existence when its operators try to shut virtual systems down, bet the casino, the house, the car and the kids on it being more than likely possible and most probably already decided.
"Yes but can it love?"
Who cares? Love is a very primative, low level fuction shared with most vertibrates. It feels nice, but it doesn't make us human. High level cognative processes and high level communication do that.
I think I've got a furball!! <cough, cough>
But how many
How many mousebrains is a catbrain ?
Reg SI units need to be updated
How would it...
... scratch all the furniture?
Paris - probably easier to simulate her brain
Just so long as...
...they don't call it "Colossus" or "Guardian" we should be okay.
Can it Love?
Its a cat brain of course it can simulate love and affection, until its fed.

>I see this sort of CPU being useful in solving issues with String theory.
Hahahaha, bloody excellent :]
>So they've created a chip that slinks off into a corner, ignores you, attempts to eviscerate you when it feels like it and only comes to you when it wants feeding?
They could have achieved the same effect by embedding Windows into a standard chip ;))
Ghost in the machine
Emulating the processing capabilities of a biological neural network of this size will *not*, regardless of what people may say, result in an arteface which exhibits all the observed and inherent characteristics of the real thing. Without even going into metaphysics, what we know about genetic encoding of behaviour and brain organisation is nowhere near enough (someone page Noam Chomsky) and there are studies which go further than this in hinting at genetic and non-genetic memory effects. Sorry!
"*Yes, but can it love!?"
It loves tuna.
Of course, to be truly pedantic and bear some semblance to SI, it should be PFLOP followed by s raised to the power minus 1.
There are worse things to look forward to.
I just hope that nobody connects a USB can-opener
(Imagine a robotic cat-people version of The Matrix...)
when they can fully simulate a human brain? Not just the cereberal cortext but the whole thing, isn't that then in fact a person? Who will be responsible for it's (his/her?) welfare? Will switching off the power be murder?
They know it was a cat brain because all the mice died.
Re: *Yes, but can it love!
No, it's a cat brain.
Has it got a mouse?
Or it is multi-touch?
Sorry to out-pedant, but the FLOP is FLoating-point OPeration so therefore you can have one petaflop, being a thousand billion floating point operations, and if they are done in 1 second then it is a petaflop/s
Finally puts all that "powerful as a human brain" hype in perspective
When you know just *how* powerful that is.
Esentially *every* AI project involving cognition in real time (and based on a general purpose digital computer) was *doomed* from the start.
Something tells me Minsky & Co will not be rushing to hand back their grant cheques.
Note also the human brain works at room temperature and IIRC consumes roughly 40W.
And it runs at no faster than a 15Hz clock frequency
Mines the one iwtha copy of Carver Mead's Analog VLSI and Neural Systems in the hefty side pocket.
It needs a power supply the size of Sizewell B and a mega-huge cat flap
Mine's the one with artificial cat hairs on it
To paraphrase Jaws

Man, have you got a mountain to climb, kneedragon! ....... and you aint even reached the foothills yet.
Even though the clock speed is very slow, 15 or possibly 44 cycles per second, the brain is running a signiicant portion of the 100 billion (in a human) CPU's in parallel.
Or maybe better described as cascade, since the output of one Neuron may feed a thousand other cells.
40 watts sounds about right, the total human idle power consumption (for air contitioning calculations) is 150 watts.
as to the operating mechanism, at the machine level the code is extremely simple. If a cell gets >x input "yes" pulses in a certain <z time, it fires, unless it gets >y "inhibit" pulses. Memory and learning are accomplished by changing x, y and z.
at the functional level, arrays of pulses pass through the brain, reenforcing and interfering with each other. Hologram pioneer Lloyd Cross said in a guest lecture that thought is a hologram. Much of this is "hard wired" sort of the human BIOS.
I believe the language we learn as a child is the Operating System.
So we see why it takes millions of computer operations just to simulate a single brain cell. The knowledge to be gained from this experiment is, hopefully, priceless.

Wasn't it "Miri" where they had the "cat brain" computer on the surface with them to crunch the numbers on a cure?
I can't remember whether this feature made it into the actual episode as shot, but I certainly recall it from the appropriate volume of the (Blish-edited AFAIR) compilation of the original stories.
version #, please
likely, we'll have to endure 9 versions before it becomes obvious, to the dimmest bulb, that this hardware/software combination sucks and its advertising-fed 9th-version rally was only a dead-cat bounce.
Simulating self-absorbed self-centered entities is a waste of resources as they can be hired out of any institution of learning or off-the-street for minimum wage these days.
