And the main comment thinks the whales will have the brains to understand something like space travel or why we desire it?
Then again, you give me an inkling what humans trying to talk to whales will be faced with.
Because I think your analogy is piss poor? Sorry to have contradicted you, Omniscient One! Get the fuck off your high horse, you're nothing special and that was downright offensive and absolutely uncalled for.
If a species has the cognitive capacity that would be required for a language akin to ours (or even more complex than it?) then why do you assume that they wouldn't have concepts like ego, greed, brutality? We already know that animals use tools; what is a weapon but a tool for the purpose of brutality?
Your example of teaching an alien all of humanity in 5 minutes, though: it's silly, and I don't think anyone in the debate here (except, you, apparently) expects that we are going to meld minds with whales in that short a time.
