Please correct me if I flub the details here, but I think it was in the Neil Gaiman episode The Doctor's Companion where the Tardis becomes a woman. We find out that the Doctor actually stole her from a museum because he thought she was so beautiful even if hopelessly outdated.
This begs the question: if by that point Time Lords no longer used Tardis's to travel through space and time, what method or technology did they use? Or did they simply no longer do so, since they had devolved into a decadent society where they looked down on anything so menial as actually traveling to lord over the time they claimed lordship over? I get the feeling it was more the latter, but I'm curious if we actually know?
Please note that in well aware of how much the history has changed over the decades. Since this was a story told in the modern who-verse, I'm primarily interested in answers from the modern who-verse.
