Emerging technologies

Many different forms of human enhancing technologies are either on the way or are currently being tested and trialed. A few of these emerging technologies include:
human genetic engineering Human genetic enhancement or human genetic engineering refers to human enhancement by means of a genetic modification. This could be done in order to cure diseases (gene therapy), prevent the possibility of getting a particular disease (similar ...

Speculative technologies

A few hypothetical human enhancement technologies are under speculation, such as:
mind uploading Mind uploading is a speculative process of whole brain emulation in which a brain scan is used to completely emulate the mental state of the individual in a digital computer. The computer would then run a simulation of the brain's information ...
, exocortex, and endogenous artificial nutrition. Mind uploading is the hypothetical process of "transferring"/"uploading" or copying a conscious mind from a brain to a non-biological substrate by scanning and mapping a biological brain in detail and copying its state into a computer system or another computational device. Exocortex can be defined as a theoretical artificial external information processing system that would augment a brain's biological high-level cognitive processes. Endogenous artificial nutrition can be similar to having a radioisotope generator that resynthesizes glucose (similarly to photosynthesis), amino acids and vitamins from their degradation products, theoretically availing for weeks without food if necessary.


Nootropics

There are many substances that are purported to have promise in augmenting human cognition by various means. These substances are called nootropics and can potentially benefit individuals with cognitive decline and many different disorders, but may also be capable of yielding results in cognitively healthy persons. Generally speaking, nootropics are said to be effective for enhancing focus, learning, memory function, mood, and in some cases, physical brain development. Some examples of these include Citicoline, Huperzine A,

and Sulbutiamine. Some authors have explored nootropics as relationship enhancements to help couples maintain bonds over time.


Ethics

Much debate surrounds the topic of human enhancement and the means used to achieve one's enhancement goals. Ethical attitudes toward human enhancement can depend on many factors such as religious affiliation, age, gender, ethnicity, culture of origin, and nationality. In some circles the expression "human enhancement" is roughly synonymous with

Since the 1990s, several academics (such as some of the fellows of the Institute for Ethics and Emerging Technologies) have risen to become advocates of the case for human enhancement while other academics (such as the members of President Bush's Council on Bioethics) have become outspoken critics. Advocacy of the case for human enhancement is increasingly becoming synonymous with "

has shown some concern that, within the century, humans may be required to merge with this technology in order to compete in the marketplace. Enhanced individuals have a better chance of being chosen for better opportunities in careers, entertainment and resources. For example, life extending technologies can increase the average individual life span affecting the distribution of pension throughout the society. Increasing lifespan will affect human population further dividing limited resources such as food, energy, monetary resources and habitat. Other critics of human enhancement fear that such capabilities would change, for the worse, the dynamic relations within a family. Given the choices of superior qualities, parents make their child as opposed to merely birthing it, and the newborn becomes a product of their will rather than a gift of nature to be loved unconditionally.


Effects on Identity

Human enhancement technologies can impact human identity by affecting one's self-conception. The argument does not necessarily come from the idea of improving the individual but rather changing who they are and becoming someone new. Altering an individual identity affects their personal story, development and mental capabilities. The basis of this argument comes from two main points : the charge of inauthenticity and the charge of violating an individual's core characteristics.
