Do you think we'll have a future with something you call, uh, afterlife? We'll have avatars that mimic increasingly better and better our behavior, our appearance, all that kind of stuff, even though those are perhaps no longer with us. Yes, I mean we need

some information about about them. I mean, think about my father. I have what he wrote. Now, he didn't have a word processor, so he didn't actually write that much, and our memories of him aren't perfect. So how do you even know if you've created

something that's satisfactory? Now you could do a rake Frederick Kurzweil Turing test. He seems like Frederick Kurzweil to me, but the people who remember him like me don't have a perfect memory. Is there such a thing as a perfect

memory? Maybe the whole point is for him to make you feel a certain way. Yeah, well I think that would be the goal. And that's the connection we have with loved ones. It's not really based on a very strict definition of truth. It's more about the experiences we share. Yeah.

And they get more through memory, but ultimately they make us smile. I think we, we definitely can do that, and that would be very worthwhile. So do you think we'll have a world of replicants, of copies? Would there be a bunch of Rakers as well?

Like I could hang out with one. I can download it for five bucks and have a best friend Ray. And, uh, you, the original, you wouldn't even know about it. Um, is that, do you think that world is, um, first of all, do you think that world

is feasible and do you think there's ethical challenges there like how would you feel about me hanging out with a replicant of you and you not knowing about it?  Doesn't strike me as a problem, um, which would you, the original, would you, would that cause a problem for you?

No, I, I would really very much enjoy it.  No, not just hanging out with me, but if somebody's hanging out with you, a replicant of you, well, I think I would start, it sounds exciting, but then what if they uh, start doing better than me

and and take, take over my friend group and then and then I'll because because they may be um, an imperfect copy or there may be more social or these kinds of things and then I become like the old version that's not, not nearly as exciting.

Maybe they're a copy of the best version of me on a good day. Yeah, but if you hang out with a replicant of me and that turned out to be successful, I'd feel proud of that person because it's based on me, so it's, it, but it is a kind of

death of this version of you. Well, not necessarily, I mean you can still be alive right, but and you would be pro, okay, so it's like having kids and you're proud that they've done even more than you were able to do. Yeah, exactly. Uh, it does bring up new issues but

uh, it seems like an opportunity. Well, that, that replicant should probably have the same rights as you do. Well, that, that gets into a whole issue. [Music] Uh, because when a replicant occurs, they're not necessarily going to have your rights, and if a replicant occurs to somebody

Who's already dead, do they have all the obligations and that the original person had? Did they have all the agreements that they had? So I think you're going to have to have laws that say, yes, there has to be if you want to create a

replicant, they have to have all the same rights as human rights. Well, you don't know someone could create a replica and say, well, it's a replicant, but I didn't bother getting their rights. And so yeah, but that would be illegal. I mean,

like if you do that, you have to do that in the black market. You have to if you want to get an official replica. Okay, it's not so easy. Suppose you created multiple replicants. Uh, the original rights, uh, maybe for one person and not for a whole

group of people. Sure, so uh, so there has to be at least one and then all the other ones kind of share the rights. Yeah, I just don't, I don't think that that's very difficult to conceive for us humans, the, the, the, the idea

that has certain, I mean, I've talked to people about this, including my wife, who would like to get back her father, and she doesn't worry about who has rights to what. She would have somebody that she could visit with and like give her some satisfaction uh

and they wouldn't, she wouldn't care about any of these other rights. What does your wife think about multiple array cores? Walls? Well, you had that discussion. I wouldn't address that. Whether I think, I think ultimately that's an important question, loved ones, how they feel about there's a, there's

something about love, well that's the key thing right? If the loved one's rejected, it's not gonna work very well. So, so the loved ones really are the key to determine whether or not this works or not, but there's also ethical rules um we have to contend with the idea and

we have to contend with that idea with AI, but what's going to motivate it is, I mean, I talk to people who really miss people who are gone and they would love to get something back even if it isn't perfect and that's what's going to motivate this

and that person lives on in some form and the more data we have the more we're able to reconstruct that person and allow them to move on right? And eventually, as we go forward, we're going to have more and more of this data because we're going to have

nanobots that are inside our neocortex so we're going to collect a lot of data. In fact, anything that's data is is always collected. There's something a little bit sad which is becoming, or maybe it's hopeful which is more and more common these days

which when a person passes away you have their Twitter account, you know, and you have the last tweet they tweeted, like something and you can recreate them now with large language models and so on. I mean, you can create somebody that's just like them and can actually continue

to communicate. I think that's really exciting because I think in some sense like if I were to die today, in some sense I would continue on if I continued tweeting. I tweet therefore I am. Yeah, well in some sense, I mean that's one of the advantages of a replicant.

that can recreate the communications of that person, you
