That, and with the other thing in the movie where they show people with limbs removed with shiny new bits about to be added. Gross, true, but why wouldn't they do to the Enterprise crew in FC what they had done to Picard, when they rebuilt him better, stronger, and faster, as Locutus in TBOBW, by put the arm sheath with electric egg whisk attachment enveloping over his arm - never mind the radiator tubes and chestplate exoskeleton and laser pointer cat toy by his ear - what would happen to his biological bits underneath? Would it all dissolve over time? Do Borg teleport the non-cranial innards elsewhere? Is the skin and bone and cartilage and muscle broken down into energy by the electronic/machine components?
