By the year 2050, we will have genetic enhancement and upgrades. Enhancement is making current genes better then they already are – for example, to make the body absorb nutrients ten percent more efficiently. Genetic upgrades are about either replacing the genomes that are bad for the body and survival or taking advantage of animal DNA by replacing human DNA with it.
Imagine being able to have the sense of smell of a dog, the hearing of a bat or the eyesight of an eagle. Naturally, by the end of the 2050's, we might see physically altered individuals who change their sex or modify their appearance to resemble a wolf.
Military will use the technology for creating genetically enhanced combat units: chimeras or completely artificial beings, who are both lethal to the enemy and completely loyal to their commanders. Genetic soldiers will have special muscular or cerebral upgrades and enhancements to survive and fight better.
