Medicine and technology (like all human progress) do not stand still. We are seeing ever more successful studies and examples of practical implementation in such areas as: prosthetics; implantation; functional exo-tools for simplifying various tasks; cultivation of artificial cells and tissues for restoring injured areas of the body. It is hard to imagine that there won't be plenty of supply from cutting-edge science and demand from those wanting to augment themselves. Improvements to the human body will become mainstream.
For example, biomechanical hands will give the average person Herculean strength. This advanced area will likely encompass the development of other improvements such as the use of prosthetic limbs and implants to overcome physical disabilities resulting from wars or industrial accidents, enhancing the human body in the process. Besides restoring lost functionality, such artificial limbs can give the wearer added capabilities.
Result: a possible scenario is the simultaneous development of exo-technologies and restoration (artificial cultivation and/or prosthetics), raising humanity to a new level of evolution. In addition to restorative prosthetics and external "upgrades," various individual characteristics will be enhanced through augmentation and implantation.
In 2050, augmentation will be at a high level in terms of performance and reliability; the consumer base will be wide, and the ethical and legal norms governing the work of manufacturers and researchers will be far-reaching. As will the rights, limitations, and permissions of end users.
