Change propagation updates are pending (496 jobs estimated) and it is recommended to wait with modifications to a category until the process has been finalised to prevent intermediary interruptions or contradictory specifications.
Earth technology is a category similar to, but different from the human technology category. Because humans populated so many other worlds, there's plenty of technology which is human, but not "of Earth". Thus, the pages below are human-made and Earth-made. Category:Silurian technology is included as a subcategory of this one, because no extra-terrestrial Silurian technology is known to exist.
