Brain–computer interface in the context of Avatar (franchise)

Superhumans are humans, humanoids or other beings with abilities and other qualities that exceed those naturally found in humans. These qualities may be acquired through natural ability, self-actualization or technological aids. The related concept of a super race refers to an entire category of beings with the same or varying superhuman characteristics, created from present-day human beings by deploying various means such as eugenics, euthenics, genetic engineering, nanotechnology, and/or brain–computer interfacing to accelerate the process of human evolution.

Throughout history, the discussion of superhuman traits and the idea of the ideal human in physical, mental, or spiritual form has influenced politics, policy, philosophy, science and various social movements, as well as featuring prominently in culture. Groups advocating the deliberate pursuit of superhuman qualities for philosophical, political, or moral reasons are sometimes referred to as superhumanist.

A superintelligence is a hypothetical agent that possesses intelligence surpassing that of the most gifted human minds. Philosopher Nick Bostrom defines superintelligence as "any intellect that greatly exceeds the cognitive performance of humans in virtually all domains of interest".

Technological researchers disagree about how likely present-day human intelligence is to be surpassed. Some argue that advances in artificial intelligence (AI) will probably result in general reasoning systems that lack human cognitive limitations. Others believe that humans will evolve or directly modify their biology to achieve radically greater intelligence. Several future study scenarios combine elements from both of these possibilities, suggesting that humans are likely to interface with computers, or upload their minds to computers, in a way that enables substantial intelligence amplification. The hypothetical creation of the first superintelligence may or may not result from an intelligence explosion or a technological singularity.

In philosophy, the brain in a vat (BIV) is a scenario used in a variety of thought experiments intended to draw out certain features of human conceptions of knowledge, reality, truth, mind, consciousness, and meaning. Gilbert Harman conceived the scenario, which Hilary Putnam turned into a modernized version of René Descartes's evil demon thought experiment. Following many science fiction stories, the scenario involves a mad scientist who might remove a person's brain from the body, suspend it in a vat of life-sustaining liquid, and connect its neurons by wires to a supercomputer that would provide it with electrical impulses identical to those a brain normally receives. According to such stories, the computer would then be simulating reality (including appropriate responses to the brain's own output) and the "disembodied" brain would continue to have perfectly normal conscious experiences, like those of a person with an embodied brain, without these being related to objects or events in the real world. According to Putnam, the thought of "being a brain-in-a-vat" is either false or meaningless.

Considered a cornerstone of semantic externalism, the argument produced significant literature. The Matrix franchise and other fictional works (below) are considered inspired by Putnam's argument.

Avatar is a 2009 epic science fiction film written and directed by James Cameron. It features an ensemble cast including Sam Worthington, Zoe Saldana, Stephen Lang, Michelle Rodriguez, and Sigourney Weaver. Distributed by 20th Century Fox, it is the first installment in the Avatar film series. The film is set in the mid-22nd century, when humans are colonizing Pandora, a lush habitable moon of a gas giant in the Alpha Centauri star system, in order to mine the valuable unobtanium, a room-temperature superconductor mineral. The expansion of the mining colony threatens the continued existence of a local tribe of Na'vi, a humanoid species indigenous to Pandora. The title of the film refers to a genetically engineered Na'vi body operated from the brain of a remotely located human that is used to interact with the natives of Pandora called an "Avatar".

Development of Avatar began in 1994, when Cameron wrote an 80-page treatment for the film. Filming was supposed to take place after the completion of Cameron's 1997 film Titanic, for a planned release in 1999; however, according to Cameron, the necessary technology was not yet available to achieve his vision of the film. Work on the fictional constructed language of the Na'vi began in 2005, and Cameron began developing the screenplay and fictional universe in early 2006. Avatar was officially budgeted at $237 million, due to the groundbreaking array of new visual effects Cameron achieved in cooperation with Weta Digital in Wellington. Other estimates put the cost at between $280 million and $310 million for production and at $150 million for promotion. The film made extensive use of 3D computer graphics and new motion capture filming techniques, and was released for traditional viewing, 3D viewing (using the RealD 3D, Dolby 3D, XpanD 3D, and IMAX 3D formats), and 4D experiences (in selected South Korean theaters). The film also saw Cameron reunite with his Titanic co-producer Jon Landau, whom he would later credit for having a prominent role in the film's production.

Mind uploading is a speculative process of whole brain emulation in which a brain scan is used to completely emulate a person's mental state in a digital computer. The computer would then run a simulation of the brain's information processing, such that it would respond in essentially the same way as the original brain and have a sentient conscious mind.

Substantial mainstream research in related areas is being conducted in neuroscience and computer science, including animal brain mapping and simulation, development of faster supercomputers, virtual reality, brain–computer interfaces, connectomics, and information extraction from dynamically functioning brains. Supporters say many of the tools and ideas needed to achieve mind uploading already exist or are under active development, but they admit that others are as yet very speculative, though still in the realm of engineering possibility.
