      Only a tiny fraction of that amount is going into alternative paths.
      Quantum dots were predicted to replace CMOS image sensors years ago, but nothing is forthcoming simply because the industry investment in CMOS sensors is too high and QD's are not regarded as enough of a benefit to pull money away from CMOS sensor improvement research.
      You can create a revolutionary memory tech for not a huge amount of money in a lab like Rice university - but making a chip using it that scales to competitive bit density with a modern 3D NAND chip costs a frickin shipping port full of money to engineer in staff and time, only compounded by the lesser experience and knowledge with the newer technologies in the industry.
      There are some things that are being pursued more vigorously, such as metalenses - they can be produced faster, more cheaply than conventional lenses and offer dramatically increased compactness + utility as a single achromatic metalens element can replace many in an optical system by focusing all wavelengths onto a sensor in one super thin piece rather than needing one element per wavelength and others for extra adjustment.
      So they are basically winners across the board relative to the technology they aim to replace. 20 years from now we will wonder why cameras lenses ever used to be so heavy.

      To some degree the energy consumption hasn't fallen, especially with desktop PCs, but the greater energy efficiency has made possible all sorts of new form factors which are much more energy efficient: laptops, netbooks, tablets, smart phones and smart watches. Eventually we will get to smart glasses, smart earbuds and smart clothes that are extremely energy efficient and can replace much of the functionality of traditional PCs. If you look at energy consumption in advanced economies, it is actually falling, which is an indication that we are doing more with less energy.
      As a computer programmer, I can tell you that energy efficiency is becoming increasingly important in programming. Not only are programmers focusing more on code that can deal with low energy systems running on a battery, but they are focusing more on compiled languages, such as Rust, Swift, Go and Julia, that use less memory and computing cycles than interpreted languages.

      @@michaeledwards2251 Hardware implementation of typing, inheritance and bounds as of yet hasn't been able to make any of these things faster for code that does these things as of yet:
      - Inheritance is basically a fancy jump instruction. The main problem with this is that with inheritance, your jump address usually has to be loaded from memory, which can take many cycles, and the CPU has to basically guess the branch target and run a whole bunch of speculative instructions while the address loads for real. Having a special version of "jump to variable address" just for inheritance just doesn't gain much over the regular variable jump.
      - Bounds is likewise a fancy conditional branch. Conditional branches that rarely get taken are already quite cheap on modern CPUs - they do take up slots in the instruction decoder and micro-op execution but they don't compete for the really important slots (memory loading/storing). In fact, loading the bound is definitely slower than testing it (since it uses a memory load instruction). The speed gain from adding hardware bounding tests is likely to be rather small.
      - Typing is in a similar situation. Usually dynamic typed variables are either just dynamic versions of small fixed-size static types (double, float, bool, int32_t, int64_t) or larger dynamic-sized variable types (strings, objects, maps, etc). The larger dynamic-sized types have to be handled in software (too complex for hardware), so you'd still have to load the type and test for it. The small fixed-size types could conceivably be handled in hardware but you'd probably just be using the largest type all the time.

    Most of the data that moves around a server farm, goes over copper. Even when computers are paralleled.
    Light travels through fiber at 65% speed of light, through copper at 60%.
    The devices that convert data to light have the same limits as the devices that drive wire.
    Light can send more than one signal using color, but that only uses a small slice of the available bandwidth.
    Copper wire operates at a lower frequency (maybe 10GHz vs 50,000GHz), but uses the entire bandwith of the wire.
    The big advantage fiber has is how far a signal can travel.

    We could:
    - use the programming languages C or Rust instead of popular programming languages like Python (which is something like 45 times less efficient)
    - use RISC based CPUs such as ARM chips or RISC5 chips
    - underclock CPUs so that they maximise power efficiency rather trying to maximise performance
    - use operating system drivers that aim to use minimal power
    If we did these things we could probably use < 1% of the power we currently use. We don't do these things largely because it would be slightly more inconvenient and would require social change rather than innovations in technology.

    Progress is not tied to computers getting better, it is contingent on excising technology from our lives. Apparently these folks failed to learn Jevon’s paradox: “an increase in efficiency in resource use will generate an increase in resource consumption rather than a decrease”. Nor do they consider the exponential power of compound growth to exceed any linear reduction or transition. Even the Greeks knew Sisyphus would never get the boulder to the top of the hill, yet techno-utopians gleefully assume a smaller transistor is going to solve all problems.

I gather the only supercomputer that's faster, doesn't exist. 44,000 watts, perhaps it could two jobs at once, heating water in the room while predicting the future, it's that fast. You know like when you make a movie and it takes forever for the processor to get done with it. Pictures simulating a nuclear explosion, fluid dynamics. Current supercomputers draw the event much slower than it happens in actuality. This chip can do more work faster and predict the event accurately in great detail faster than it can occur.

Yes, heat pumps are way more efficient for heat (300-400%) computer chips are “only” ~100% efficient in producing heat. That heat would otherwise be discarded, which costs more energy, so by using it we are reducing our electricity required.

    It is interesting that you can’t combine some of these methods as with neuromorphic computing or neural networks , you could use the efficiency of say photonics but the problems with all these chips is running things like an operating system on top of them as photonics wouldn’t struggle with quantum mechanics problems and as photons are smaller than electrons . The problem is that you have to convert electricity to light using oleds,
    Neuromorphic computing could solve the carbon nanotube problem but the problem is that you can’t get smaller than the carbon atom which is essentially quite big as it has 14 proton and neutrons. To separate them if it is metallic you would just need a magnet.
    The thing is to arrange them on a chip would be the most fascinating thing as you could use a neural network to align the chips in the best configuration
    Light to me is the best option with a neuromorphic setup but to make light travel as it has different wavelengths on the electromagnetic spectrum ,
    But even if you have light together it is still going to generate heat or if you have light transistors . As you could go down to the width of a photon in electronics or photonics , how can you tell whether a light transistor is on or off. If light has mass that would make a difference. You could control light if it was moving at a specific frequency say red shifted.
