Well, the one thing that did change at that juncture was that the Talosians got two human women. After that, they initiated the information hijack, and Spock may well have been correct in his interpretation that they did this merely because they wanted to destroy the ship (now that they had everything they wanted), and saw some incidental merit in robbing the ship before destruction.Plot hole: Why did the Talosians wait so long before scanning the Enterprise's memory banks? Why didn't they learn as much as they could about human history and culture as soon as they had Pike in captivity?
Capturing members of all sexes would seem like an obvious criterion for success. Perhaps the Talosians were seasoned abductors in this respect, and well knew that they had to treat their prey with velvet gloves until this goal was reached.
Learning about their captives would never have been a priority for the Talosians - what possible advantage would that give, when the captives were already nicely under control and would soon forget all about their previous life and so-called culture?
Was it? Some recent research suggests that inbreeding is much less of a problem than previously thought (although that admittedly pertains to somewhat larger inbreeding populations). And the technology to correct the worst problems might be relatively primitive, far from divine - us puny humans might well master it in the next five years.Unless the Talosians were divine, then I assume their desire to create a race of humans from breeding just 2 of them, was destined for failure.
Perhaps more significantly, Talosians might not need a "race" of humans. Just, say, four or five generations of slaves might be enough to get their civilization back up and running, in their own (probably quite unrealistic) projections. And after that, it's a big bonus if the slave race degenerates and dies out. Saves the Talosians the expenses of execution pits.
