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)

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 civlisations that eventually developed technology. The Second Doctor found that: "At various points in its long and very varied history, the human race questions where it's going – what it might become. And, sometimes, they worry that they've come too far from whatever they were before. Every highly evolved industrial society, on every planet, throughout history, creates a group who reject that technology. Who choose to live a life outside the cities, close to the earth. They might be religious, political – maybe they're just following a dream of ancestors. Looking for an Eden. I don't know. But they think it'll bring them closer to what it means to be human."

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 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)
