Who sent the Whale Probe and what their relationship was with Earth's Humpback Whales in the ancient past.
There are plenty of things I want to know more about, and there some things I think are better left unanswered.
This is one of the latter. It's interesting to ponder, but I feel like any answer they give us won't live up to the expectation and wonder.
Same with V'Ger, and to a lesser extent, the Borg. We COULD do a Borg origin story but I feel like it's kind of mundane. I really don't think there would be a huge, dramatic, dynamic story around the formation of the Borg. Rather, I think it's closer to a long, drawn out, Cyperpunk-eque story where a planet dabbles into cybernetics and it slowly consumes them. Interesting enough on it's own, but I don't see a single climax moment. It's more of a progression. Even the Collective I think starts small, on the planet and the first people they assimilate are themselves. I have toyed with that idea and have some half-finished writings about it, inspired by Cyberpunk stories. My idea was that there's a very like, Cyberpunk 2077ish world and cybernetics are running amok as well as unchecked consumerism and consumption. The Collective is actually a backfired tactic enacted by a corporation trying to exploit brain-mods to gently mind control the masses. It works... sort of... but rather than giving them the power to influence the masses, it actually just networks them together. The new collective starts to spread with basically a single focus... "consume".
