Part 4/10:
The crux of Nathan's experiment is the Turing Test, a measure of a machine's ability to exhibit intelligent behavior equivalent to, or indistinguishable from, that of a human. Nathan reveals to Caleb that he has created an advanced AI named Ava, who he believes is on the cusp of passing this test. Caleb's intrigue is palpable; he understands that if Ava passes, it would signify a monumental leap in human understanding of consciousness.
While Caleb prepares to interact with Ava, he notices a crack in the glass barrier housing her, hinting at Ava's awareness of her confinement and a desire for escape. Their initial meeting is electric, as Caleb finds himself captivated by Ava’s humanoid appearance and evocative conversation.
