so we all agree that the finetimers are extremely puritanical as a culture, right? no way are these people fucking. apart from the ānever been hugged beforeā scene (space babies parallel, iāll come back to that) and the fact that they seem initially opposed to any kind of in-person interaction, thereās not much textual evidence that points towards it, but itās quite easy to extrapolate. an isolationist, white-supremacist colony of post-humans thousands of years into the future, genetically engineered to have blue blood (a symbol of aristocracy) running through their veins ā itās not exactly a stretch to suggest that a culture such as theirs would view sex + sexual reproduction as something uncouth, āuncivilisedā, taboo, base and āprimitiveā.
as for babymaking? these people definitely make use of āparthenogenesis machinesā as seen in space babies. in fact, theyāre 100% ardent supporters of eugenics and probably pre-select the most ādesirableā traits for their infants to develop.
the parallels between finetime and gallifrey have been pointed out before (iāll tag the post in the comments if anyone asks), but hereās another one. iām quite certain that the residents of finetime, and finetimeās homeworld, create their children with looms looms iām trying to type something else but it keeps correcting to āloomsā those fetus tanks from space babies. you know. another penny in the āruby was artificially createdā theory jar, more doctor/ruby parallels, and a snazzy bit of worldbuilding
