If fictional media is anything to go by, the single defining aspect of human intelligence is love. This is the last bastion of human understanding that is incomprehensible to evil, machines and aliens.
Humans can already fall in love with computers and virtual personalities, so we're halfway there
But love is indistinguishable from a set of actions that we traditionally associate with love, any of which a computer system (especially one connected to a realistic android) could conceivably perform.
Depends on your choice of fictional media; try reading Peter Watts, some time when you're already not in a good mood.
Thanks, I'll place Blindsight by Peter Watts in my queue.
That's the place to start; the Behemoth trilogy isn't bad, per se, but it is a ramshackle thing by comparison, and I think only partly because it has a larger story to tell.
