Technology

Technology were the tools used by a civilisation. According to Clarke's Law, "Any advanced form of technology is indistinguishable from magic." (TV: Battlefield)
The first Gallifreyan time machine, the Time Scaphe, was powered psychically rather than technologically. (PROSE: Cat's Cradle: Time's Crucible) The Archons claimed that the Time Lords didn't discover time travel for themselves, but developed it after they declared war on the Archons and stole their technology. (PROSE: The Nameless City) An early Time Lord colonisation effort forced the colonists to surrender their advanced Gallifreyan technology. (COMIC: Origins)
The Neo-Technologists, led by Rassilon, rose to power on Gallifrey, overturning its matriarchal society based on magic and superstition. (PROSE: Cat's Cradle: Time's Crucible)
Humans were among civilisations that eventually developed technology. The Second Doctor found that:
The Nestene Consciousness identified the Doctor's TARDIS as superior technology. (TV: Rose)
The uneasy truce that the Papal Mainframe enforced during the Siege of Trenzalore prohibited any sufficiently advanced technology in the town of Christmas, with the exception of the Doctor's sonic screwdriver, which was present before the truce was established. The Wooden Cyberman was created as a "low-tech" weapon to bypass this and enter the town. (TV: The Time of the Doctor)
The crowing technological achievement of the Exxilons was their Great City. Built too-well however, the city's beacon drained all energy on Exxilon to repair itself, depowering all technology and causing its builders to regress into a stone-age species that distrusted technology. (TV: Death to the Daleks, PROSE: Death to the Daleks)
Survivors of the 2150s Dalek invasion of Earth believed that the occupation had set humanity's technological progress back by roughly two centuries. (AUDIO: An Earthly Child, After the Daleks)
