Hugh Darrow's "Final Interview"
HUGH DARROW: The fact is, Eliza, the last few years have taught me some very valuable lessons.
ELIZA CASSAN: I understand you've had some controversial things to say about augmentation technology.
HD: I've ruffled some feathers, to be sure. But I have that right.
EC: That technology wouldn't exist without you-
HD: Look, the fact is... [PAUSE] What's that bloody Einstein quote about the A-Bomb?
EC: "If only I had known, I should have become a watchmaker."
HD: Yes, that's the one. I know what he meant. These days I'm thinking we went too far. I'm wondering about putting the genie back in the bottle.
EC: Is that possible?
HD: Everything is possible. Having the ability to transcend our times is one thing, but racing uncontrolled toward some blind singularity... We're in danger of becoming two species. Those empowered... And those left behind.
