Hypothetical technology is technology that does not exist yet, but the development of which could potentially be achieved in the future. It is distinct from an emerging technology, which has achieved some developmental success. These emerging technologies include 3-D metal printing and artificial embryos. A hypothetical technology is typically not proven to be impossible. Many hypothetical technologies have been the subject of science fiction.
Artificial general intelligence (AGI) is hypothetical artificial intelligence that demonstrates a human-like ability to learn. AGI indicates a machine that could successfully perform any intellectual task that a human being can. It is a primary goal of artificial intelligence research and a common topic among science fiction writers and futurists. Artificial general intelligence is also referred to as strong AI,full AI or one that has the ability to perform "general intelligent action". AGI is associated with traits such as consciousness, sentience, sapience, and self-awareness, which are observed in living beings. Some examples of hypothetical technology are flying cars, jetpacks, teleportation, or robot helpers.
An HIV vaccine is a hypothetical vaccine which would either protect individuals who do not have HIV from contracting that virus or otherwise may have a therapeutic effect for persons who have or later contracted HIV/AIDS. Currently, there is no effective HIV vaccine but many research projects managing clinical trials seek to create one. There is evidence that a vaccine may be possible. Work with monoclonal antibodies (MAb) has shown or proven that the human body can defend itself against HIV. Certain individuals also remain asymptomatic for decades after HIV infection. Potential candidates for antibodies and early stage results from clinical trials have been announced. It is believed that "current approaches are focusing on recombinant protein and attenuated whole organism vaccines."
Malaria vaccines are an area of intensive research in an effort to cure the disease caused by parasitic protozoans (a type of unicellular microorganism) of the genus Plasmodium. The emergence of artemisinin and multi-drug resistant strains of especially P. falciparum are driving the research. Current approaches are focusing on recombinant protein and attenuated whole organism vaccines. Various vaccines have reached the state of clinical trials but most still demonstrated insufficient immunogenicity. There is no practical or effective vaccine that has been introduced into clinical practice.
Whole brain emulation (WBE) or mind uploading (sometimes called mind copying or mind transfer) is the hypothetical process of copying mental content (including long-term memory and "self") from a particular brain substrate and copying it to a computational device, such as a digital, analog, quantum-based, or software-based artificial neural network. The computational device could then run a simulation model of the brain information processing, such that it responds in essentially the same way as the original brain (i.e., indistinguishable from the brain for all relevant purposes) and experiences having a conscious mind.
Mind uploading may potentially be accomplished by either of two methods: Copy-and-Transfer or Gradual Replacement of neurons. In the case of the former method, mind uploading would be achieved by scanning and mapping the salient features of a biological brain, and then by copying, transferring, and storing that information state into a computer system or another computational device. The simulated mind could be within a virtual reality or simulated world, supported by an anatomic 3D body simulation model. Alternatively, the simulated mind could reside in a computer that's inside (or connected to) a humanoid robot or a biological body.
A space elevator is a proposed type of space transportation system. Its main component is a ribbon-like cable (also called a tether) anchored to the surface and extending into space. It is designed to permit vehicle transport along the cable from a planetary surface, such as the Earth's, directly into space or orbit without the use of large rockets. An Earth-based space elevator would consist of a cable with one end attached to the surface near the equator and the other end in space beyond geostationary orbit (35,800 km altitude). The competing forces of gravity, which are stronger at the lower end, and the outward/upward centrifugal force, which is stronger at the upper end, would result in the cable being held up, under tension, and stationary over a single position on Earth. Once deployed, the tether would be ascended repeatedly by mechanical means to orbit, and descended to return to the surface from orbit.
On Earth, with its relatively strong gravity, current technology is not capable of manufacturing tether materials that are sufficiently strong and light enough to build a space elevator. However, recent concepts for a space elevator are notable for their plans to use carbon nanotube or boron nitride nanotube-based materials as the tensile element in the tether design.
The basic idea is to take a particular brain, scan its structure in detail, and construct a software model of it that is so faithful to the original that, when run on appropriate hardware, it will behave in essentially the same way as the original brain.
