Circa [[97,445 BCE]], humans were returned to Earth and watched as the [[Portal at Voi]] was buried.

In civilian society, automated systems—sometimes controlled by the subprocesses of a larger AI—have found uses in [[roadware|piloting civilian vehicles]] as well as performing most manual labor in [[JOTUN Heavy Industries|agriculture]] and industry.<ref>''Halo Encyclopedia'', p. 42 (2011)</ref> The scale of AI-driven automation ranges from single cities to entire worlds; the former sometimes operated by a "dumb" AI such as the [[Superintendent]] while "smart" AI [[Mack]]'s oversight of [[Harvest]]'s agricultural operations is an example of the latter.

Humans have also adopted a variety of [[Human augmentation|bioengineering and augmentation]] technologies. Human enhancements saw military application in the [[Interplanetary War|first interplanetary conflicts]].<ref name="enc44">'''[[Halo Encyclopedia]]''', ''page 44''</ref> While human enhancement has been commonplace for centuries, more extensive augmentation or experimentation has been limited due to ethical concerns. An exception to this are the biochemical and cybernetic augmentations used in the [[SPARTAN programs]], which represent the peak of human medical technology in the field of biological enhancement. Human rebels also use "[[rumbledrug]]s", which degenerate the user's body but grant them superhuman abilities for a short time.{{Ref/Reuse|midlothian}}

Humanity also employs a variety of gravity-manipulating technologies, including two forms of [[artificial gravity]] aboard spacecraft and space stations. The first is a system of rotating "carousel" sections which generate an approximation of gravity through centrifugal force. There is also a form of artificial gravity which does not require moving parts, but this technology consumes enormous amounts of power and spinning sections are generally regarded as being more efficient.<ref>'''[[Halo Encyclopedia]]''', ''page 211''</ref> Some [[UNSC starship|UNSC ships]], such as {{Class|Phoenix|colony ship}}s or [[UNSC frigate]]s are equipped with a form of [[anti-gravity technology]], as evidenced by their ability to operate in a planetary atmosphere without the use of thrusters.{{Ref/Level|[[Halo 3]]|[[The Storm]]}} Not all ships are equipped for atmospheric operation, however.{{Ref/Novel|[[Halo: The Flood]]|Page=40}} Anti-gravity is not typically implemented on craft smaller than warships and conventional engine systems are used to produce lift instead.{{Ref/Novel|Halo: Ghosts of Onyx|Page=135}}
