In the tv series Westworld, Theresa Cullen and Charlotte Hale are sending data out of Westworld with the help of some re-programmed bots. This was discovered by Elsie Hughes. When they were talking about it, they explicitly state that it is not about the programming code of the bots, but rather something more valuable.
What kind of data are being sent out of Westworld? (And why are they so valuable?)
