with supercapacitors, and graphene templates nanobots may be able to produce micro welds in large enough numbers to build cylinders of crystalline super alloys of various scales, although these will initially have to be grown in low gravity environments. Nanites also have the problem of keeping track of them all, and the potential for self replication. That can be avoided if the primary components in their design uses unusual materials, such as radioactive isotopes. 3D printing will have some overlap eventually, but I'm not sure precisely what yet, other than the blue prints themselves.
In the concept of a virtual reality, there is the wall of modem speed that prevents the reality of being physically, or digitally present in some foreign, virtual environment, particularly because you normally have to upload vast amounts of virtual data over a stream, and the real time aspect of reality is lost.
Video game companies tried bypassing this by allowing players to download the bulk of the game's graphic and audio files and then keeping control over more important content. Still, this model would require everyone on earth to have downloaded every virtual reality compilation and advertising logos and audio files on Earth, and largely for no reason.
The design that makes more sense is the application of cloud processing when the processors of millions of networked computers run different important bits of information, possibly even decompiled information, and then the pilot or viewer of the internet interface then uses their console or other device to integrate the important pieces of information as they are experienced in real time. Location in cyberspace would be a side effect of what kind of data you were processing, as your system would act as a server assembly like everyone else. I haven't fully examined how this would allow for 3 Dimensional or Multidimensional Architecture, but it is reasonable to assume that if you were in a "Tokyo space" interacting with their language and media files, that someone who wanted to port into Tokyo space could arrive 'there" more quickly by connecting to "you' in real space. I believe if the theories of entanglement prove to be true in the near future, then these virtual spaces in conjunction with the cloud architecture will take on wholly new principles of telepresence.
In the mean time, this transmission disconnect can be partially mitigated by processing only the most basic essentials of the alternative reality, and leaving the bulk of the processing factors that are immediately important to the domestic networks seeding the cloud. It would be human interaction that would produce the most dissonance, although predictive programming techniques similar to the auto-complete features of a search engine might be used to attempt to extrapolate in advance the data, and send an illusionary form of that data and then auto-correcting it as the real variant arrives. This could be a confusing experience for a person witnessing the variances between true transmission and synthetic transmission, but I believe such a system might end up looking more accurate than most people's spell checked essays. Where absolute correctness was needed, buffers as once used in radio communications could be expected, but again, all of this could be overcome by entanglement processors.
"As the system learns your likes and dislikes, ... you'll discover content preloaded and ready to go on your console," said Mark Cerny, lead system architect of PS4. "Our long-term vision is to reduce download times to zero."
The PS4 will also boast a robust, cloud-enabled network that let users sample games before purchase without waiting to download.
PS4 is accurately representing the new trend of prediction.
current research indicates 3D printing will be as big as the steam engine or the computer, some say it will be bigger than the internet. Those people are probably right. Currently, a few billion dollar industry is set to explode into tens, and eventually hundreds of billions.
We are using 3D printing for prototypes, and to make molds for casting. It is also possible to 3D print a machine with all the integrated components together, with no seems. That means in the near future, you will be able to have parts with no screws or bolts holding them together, and soon those bonds will be stronger than anything seen today. Pressures will become higher and energy potentials will shortly follow.
Based on the fact that we can build machines with no seems and higher pressures, you will see advances in roller coasters, aerospace machines, and even simply things like pop up plastic cups or the gears of a bicycle.
Child's cybernetic hand produced on 3D printer at low cost. Designer makes blueprints open source so anyone can use the design for free.
People, this is only the beginning. Rapid prototyping (what people like the military call it) can be used to make a wide variety of objects where extreme materials are not necessary. As products like this become available, people will want to utilize, then improvise on them. These improvisations will lead to other models, and what you may end up seeing is product 1.0, then product 1.2, then products 1.3, 1.4, 2.0 and 2.5 being produced in extremely limited quantity as hypothetical models, followed by a mass production of product 3.0, and then the cycle may hiccup and jump again at 3.2, 3.3 and so on. That's what I meant by "bumpy". When people have resources to invest in cutting edge innovation, the hiccup happens when their resources can't keep up with the rapidity of innovation, and then when their resources such as bank accounts replenish, they then have the opportunity to buy "the latest model" but that's like light years ahead of the previous model.
Expressions like "Don't have what you want? Wait" come to mind.
