"[Nonaka and Alexa talk of converting an intelligent machine to help them] Alexa: Will it...? Do you think it will convert? Nonaka: To convert is its choice to make. Alexa: Do you think we ought to reprogram it? Nonaka: No. We can't make slaves of them. Alexa: Because that would be simpler. Nonaka: We won't beat the machines by making them our slaves. Better to let them join us by choice. Alexa: Make them believe the right choice is the one we want. Nonaka: All right. Yes, machines are tools. They're made to be used. It's their nature. Alexa: To be slaves. Nonaka: That's why we show them a better world, why they convert. Alexa: But that world we show them isn't real. Nonaka: It doesn't matter. Alexa: I'm afraid they'll figure out that we've made up the thing in our heads. Nonaka: They can't tell the difference. To an artificial mind, all reality is virtual. How do they know that the real world isn't just another simulation? How do you? Alexa: I know I' m not dreaming now because I know what its like being in a dream. Nonaka: So dreaming lets you know that reality exists? Alexa: No. Just that my mind exists. I don't know about the rest. [Allusion to Cogito, ergo sum.]"
