    Dr. Michio Kaku says "if I were to put money on the table I would say that in the next ten years as Moore’s Law slows down, we will tweak it."
    ----------------------------------------------------------------------------------
    MICHIO KAKU:
    Dr. Michio Kaku is the co-founder of string field theory, and is one of the most widely recognized scientists in the world today. He has written 4 New York Times Best Sellers, is the science correspondent for CBS This Morning and has hosted numerous science specials for BBC-TV, the Discovery/Science Channel. His radio show broadcasts to 100 radio stations every week. Dr. Kaku holds the Henry Semat Chair and Professorship in theoretical physics at the City College of New York (CUNY), where he has taught for over 25 years. He has also been a visiting professor at the Institute for Advanced Study as well as New York University (NYU).
    ----------------------------------------------------------------------------------
    TRANSCRIPT:
    Michio Kaku: Years ago, we physicists predicted the end of Moore’s Law that says a computer power doubles every 18 months. But we also, on the other hand, proposed a positive program. Perhaps molecular computers, quantum computers can takeover when silicon power is exhausted. But then the question is, what’s the timeframe? What is a realistic scenario for the next coming years?
    Well, first of all, in about ten years or so, we will see the collapse of Moore’s Law. In fact, already, already we see a slowing down of Moore’s Law. Computer power simply cannot maintain its rapid exponential rise using standard silicon technology. Intel Corporation has admitted this. In fact, Intel Corporation is now going to three-dimensional chips, chips that compute not just flatly in two dimensions but in the third dimension. But there are problems with that. The two basic problems are heat and leakage. That’s the reason why the age of silicon will eventually come to a close. No one knows when, but as I mentioned we already now can see the slowing down of Moore’s Law, and in ten years it could flatten out completely. So what is the problem? The problem is that a Pentium chip today has a layer almost down to 20 atoms across, 20 atoms across. When that layer gets down to about 5 atoms across, it’s all over. You have two effects. Heat--the heat generated will be so intense that the chip will melt. You can literally fry an egg on top of the chip, and the chip itself begins to disintegrate And second of all, leakage--you don’t know where the electron is anymore. The quantum theory takes over. The Heisenberg Uncertainty Principle says you don’t know where that electron is anymore, meaning it could be outside the wire, outside the Pentium chip, or inside the Pentium chip. So there is an ultimate limit set by the laws of thermal dynamics and set by the laws of quantum mechanics as to how much computing power you can do with silicon.
    So, what’s beyond silicon? There have been a number of proposals: protein computers, DNA computers, optical computers, quantum computers, molecular computers. If I were to put money on the table I would say that in the next ten years as Moore’s Law slows down, we will tweak it. We will tweak it with three-dimensional chips, maybe optical chips, tweak it with known technology pushing the limits, squeezing what we can. Microsoft for example, a software company, wants to go to parallel processing. Instead of having one chip here, spread them out horizontally. Take a problem, cut it in many pieces and have it run simultaneously on many standard chips. That’s another possible solution. But hey, Moore’s Law is exponential. Sooner or later even three-dimensional chips, even parallel processing, will be exhausted and we’ll have to go to the post-silicon era.
    So, what are the candidates? The first candidate is molecular computers; that is, molecular transistors. They already exist. We already have molecules that are in the shape of a valve. You turn the valve one way and the electricity stops through that molecule. You turn it the other way and electricity flows through that molecule just like a pipe and a valve because that’s what a transistor is, a switch, except this switch is molecular rather than a switch made out of piping. The problem is mass production and wiring them up. Molecules are very small...

    Mr. Michio Kaku is correct about everything in this video. Anything he describes is easy to understand even for people with limited technical knowledge. I am in the business optimizing software for various CPUs for 15 years and i am amazed about how correct he is about everything, although he is T.Physicist and not hardware/software engineer.

      that ie not true, he said it will come to an end/collaps 10 years later. In the year 2020, so 8 years later, we already know it will in fact NOT come to an end in 2022. I would even say it is already very likely it will atleast continue for atleast another 10 years.

Stanford University is researching graphene dna which does just that. Transistors in such fields can talk over distance without actual connection. Too bad they aren't growing it properly.

      D-Wave's systems so far show little or no demonstrated promises of quantum computing; www.sciencemag.org/content/345/6195/420 To be fair Quantum computing is still in its infancy, maybe the software and algorithms used in D-wave's systems are not up to snuff. Hoefully a better quantum computing system will emerge out of the Quantum gate model which is harder to do. (D-Wave uses the Quantum Annealing/Adiabetic model)

    The mistake Moore made is not normalizing by atomic weight. Engineering is a subset of chemistry and chemistry a subset of physics. Chemistry and physics deals with mass and energy. Not area or feature size. These are all derived units which really should be reduced to more basic units.
    A 100 micron thick wafer produced has been produced by DuPont. DuPont plans a printer technology that will print circuits made of solid state devices. So, we can imagine a 400 mm diameter wafer that's 0.1 mm thick -that's 12.57 cc of silicon massing 29.27 grams. 1 mole of silicon is 28.09 grams.
    With 90 nm feature size, a hexagon with a 90 nm edge is 21,044 nm2. There are 5.97 trillion hexagons inside a 400 mm diameter wafer. 204 billion features per gram. 204 trillion features per kilogram.
    Reducing this to 9 nm and 10 micron thick wafers increases this by a factor of 1000 or 204 trillion features per gram.
    www.nature.com/ncomms/2013/130619/ncomms3061/full/ncomms3061.html
    This can be compared to Avogadro's number. 6.02e23 atoms. Now recall in biochemistry we use the term Daltons as a measure of atomic weight. A carbon atom has 12 Dalton mass. A silicon atom a 28.09 Dalton mass. The DuPont tech is 82.88 giga-Daltons per feature.
    The University of Arizona has identified the protein in the neural synaptic junction that stores and processes information. Its called a microtuble. There are dimers that move up and down the microtuble moving molecules into different well-defined conformations. These molecules cause the dimers, or Tubulin, to change direction and path also in well-defined ways, making a 2 dimensional version of a Turing Machine.
    www.sciencedaily.com/releases/2012/03/120309103701.htm
    When will circuitry equal Microtublin?
    Now, the basic computational element of this molecular machinery masses about 110,000 Daltons, or 753,454x smaller than the 9 nm feature on the 10 micron thick wafer. With an 18 month doubling cycle this will take 351 months or 29.28 years to achieve this level of sophistication.
    Molecular Computing Doubling Every Six Months!
    Just as IC engineering accelerated development over that of Vacuum Tube technology, Molecular engineering is vastly easier and quicker than IC engineering.
    Given this rate of development of molecular computing, I believe we are on an accelerating curve. Yes, silicon wafer technology might be slowing down, however, it is branching off in other directions, micro machinery for example. However, molecular level computing is developing and accelerating. Doubling every 6 months if you can believe it. In that case, we can expect to reach human levels of performance in 9.76 years - by 2025.
    Human Equivalence Not Required - Thinking Required Beforehand.
    Now, I do have a caveat about this. Namely, there is a lot more to being human than functioning as an economic human unit. I believe we are already at the point where we can build robots that function as economic equivalent units. This will free humans of economic requirements, once we perfect general self-replication.
    This requires a reboot of our economic and political system, which is underway. The new system will require emergent methods of control, if you can call it that, and digital currency based on self issued credit based on maximizing total human happiness and a few other limits. Ancient cultures may help us out here. The Mayan sought cosmic meaning apparently. The Greeks sought beauty. I am looking at organizing principles now and incorporating those into my bitcoin+ work. The absolute worst investment is building artificial intelligence that is better than people at killing and fooling people. In this regard our present military industrial intelligence government system is way off track. It will produce machinery far more efficient than a-bombs and h-bombs in killing people. It will sink our civilization very shortly unless something is done to remove the mad folks running things from power.
    When will Moore's expansion end?
    We have 30 years to reach the level presently implemented in the human brain. There is no reason we cannot improve upon this design to create super-human computing. In fact, designs have already been proposed that will see a further increase by a factor of 1000 a least without changing the fundamental molecular computing paradigm we already have well understood. This is another 10 doublings which add 180 months (15 years) using the IC rate of doubling, or 60 months (5 years) using the molecular computing rate of doubling, to our earlier figures - putting the end at 2060 at the slow rate and 2030 at the higher rate- with circuitry that is 1000x more efficient than the human brain!
    Is that the end?
    No! When we deal with molecules we are approaching the quantum limit. This is not the end, but the beginning, since we can use quantum entanglement to perform quantum computations in a non-classical way.
    Also, Jacob Bekenstein showed that black holes can store and process information. String theory suggests that microscopic black holes may be possible for our particle accelerators to create. Once we have micro-black holes in our possession, they are easier to make! Interacting black holes can process information far more rapidly than possible with molecules. Furthermore, 80% or more of the matter in the cosmos may be WIMPs - weakly interacting massive particles. Stable micro-black holes the irradiate everything the same as the 3K background radiation! Once we have made a few engineered micro-black holes, it is very likely that we can use them to interact with this WIMP flux and do a number of amazing things. One of these will be to send information through time, which opens up another computational development arc;

    The future's so bright you've got to wear shades! :-)
    The Future's so Bright, I Gotta Wear Shades
    Once we signal through time any conventional measure of acceleration cannot be applied as there is no conventional limiting factor at that point. One way to think about this statement is to consider Bekenstein's equation that equates massenergy and information and Hawking radiation which extracts energy from the Zero point. Its clear that if energy can be extracted from the vacuum or disappear into the vacuum, then information can be stored and retrieved in the vacuum as well.

    Part of the problem not gone into is that of the bus choke point. No matter how fast your processor operates, you have to have a bus speed that gets information in and out of it quickly enough to take advantage of it. That's one of the reasons for parallel processing; split the task among more processors, and you widen the choke, like adding more lanes on a highway. Another solution is dynamic processing; building chips that can switch between being RAM and processor instantaneously.

    Back in 2008, I saw an ad for a High End PC with 1Tb drive, in 2010 I got myself a Middle Of The Line PC with 1Tb drive but now in 2013, most MOTL PCs still have only about 1-2Tb drives.
    In the same amount of time 10 years earlier, we went from 1Gb drives to 10Gb drives.
    In conclusion, Moore's Law is showing down.

      then you have never understood Moore's law from the beginning, it has nothing to do with storage to even begin with!
      Furthermore comparing your usecase for storage to the storage market makes it even more useless and actually very stupid.

    Im talking about using graphene as a wire substetute in molecular computers. The thing about creating processors out of graphene, from my knowledge of transistors the silicon needs to be laced with certian impurities so that the transistor would perform its function. The reason I suppose it will be hard to make a graphene processor is because it is only one atom thick and that will make it hard for the impurities to be put in.

    You could try and find a speed limit and a correlated market need to determine what the likely normal limit is. We can see with super computers that we can always use size to compensate, to some extent, anyway. There is a limit to the amount of power a person might even need, such as when nuance becomes to subtle to even be noticed, such as in a video game.

    The number of permutations for binary states of 5 atoms is 5 factorial, which is 15. Any discrete arrangement of states has 15 possibilities, of which both 5 & 3 are integer divisor subsets & prime numbers. This explanation does not describe the exact calculation process, but it does demonstrate that this calculation is possible.

    You're right that you can convey more data in ternary, but it's harder to process the data, and the net result is that ternary is slower than binary for conventional computing, hence why we don't do it.
    Quantum computing is powerful because you are 0 and 1 simultaneously, which means you can perform operations on every possible state of a system at once, but the drawback is you can only ever get ONE answer when you try to measure it.

    There exist much more significant calculations -- solving optimization problems, problems we can't even solve because the calculations are too long (NP-Hard problems). It can help businesses strategize shipping, help colleges schedule their classes without conflicts, project management.
    The people using it won't know how it does it (just like I don't know what numerical scheme Excel uses to calculate F distributions), but these too could become just another triviality for Excel.

    Parallel computing and hopefully the VLIW instruction set making it - that's what I see in the near future until quantum computers (I was told by our physics department that they are probably about 50 years away) arrive.

    Even if you have a compiler that allows you to write a quantum computer program in Java it is still fundamentally different than normal computing. For instance something simple like "int x=5;" doesn't make sense because data stored isn't in a specific quantum state it is a superposition of states so it could look something like "int x = 1 or 2 or 3 or 4 or 5"

    When was this recorded?
    I thought the 5 qubit IBM results were done ~2003. The approach was self limiting and research has taken a different direction since then, in particular with error correction qubits (ie computation + memory) eg Yale has an operating 4 qubits with error correction that handles a number of algorithms, and Delft has developed something similar.
    Maybe public availability will be slowed the military code breaking applications rather than the technology itself.

    @Surtak Před 12 lety

    Well the point is that it isn't the number of possible states that increases speed, but really how quickly you can change between them. A ternary system might have to switch all three states rather than two, which makes me believe it might be slower. It might perform the same as binary, but I don't think it would give any reason to be faster.

    he's talking about the point when these transistors reach a threshold where information processing becomes so fast problems such as critical overheating or loss of data might occur. you obviously don't think that when something reaches it's physical performance pinnacle that it can still go further. Everything in a physcial state has a limit and same applies to transistors, and he's talking about quantum computing, computing in teraflops, not just a handful of teraflops mind it!

    If you mean to counter the uncertainty principle, i am not sure if that will work because as far as i know it doesn't matter if the wire is insulated by whatever material because the electrons can be anywhere in a certain radius.
    But i think graphene can also be used as a semiconducter to make the circuits wich will have greater conductance = less heat and operate on higher frequencies.
    And can't Michio Kaku make a video on the possibilities of graphene? :D

  • @stepback1317
    @stepback1317 Před 12 lety

    The breakthroughs in quantum computing have been huge, but they are all limited to a small number of qubits. Preskill (1998) calculated that you'd need about a million qubits for a quantum computer to outperform the best classical ones. Recently, an NMR group in Shanghai factorised 143 into 13x11 using FOUR qubits. This is a huge step, but it is still a VERY long way from a million qubits!
    Scaling a quantum computer from a few qubits to a million, interconnected ones is going to take decades.

    In the future, or in one or more pararel universes, we have the power to travel in time.
    This would provide the fascinating ability to study ones origins.
    a) Could UFOs belong to time travelers?
    b) would the contact with them explain the knowledge of our galaxy present in past civilizations?
    c) If they helped us in the past, were are they now?
    Could their influence had changed our timeline, preventing us from reaching type 1 or above?

    From what I just read in that report, "they may not be made of silicon at that point" which is what Dr. Kaku is referring to. There are a number of people in the technology field that estimate approximately a decade before problems begin to arise, so I certainly don't think Dr. Kaku is "completely wrong" and that "the video should be removed".

    Thats more or less what they already do. Although difficult, we can shield the atoms from outside disturbances well enough by putting them in a sealed box. The issue then, becomes one of how to take a reading of the atoms while theyre inside the sealed box without disturbing them. You have to put a sensor inside the box too, and the consequences of doing that are obvious.
