Summary

An interview with Ariel Zeleznikow-Johnston, author of the book 'The Future Loves You: How and Why We Should Abolish Death'. We begin by discussing how best to define death, focusing on the idea of death as the permanent disruption of psychological identity, and how such identity is constituted by our personality, desires, and memories. We then consider the science of brain preservation, including the recently-developed technique of Aldehyde-Stabilized Cryopreservation, and how it could be used to indefinitely preserve the brain structure that encodes or personal identity. Ariel argues that such a preserved brain could potentially be used to construct a digital simulation of our brains, essentially allowing us to survive the biological death of our bodies. We conclude by considering some potential challenges of implementign such a technology, and whether it would achieve widespread social acceptance.

Oh, wow, oh, oh, wow, oh, wow, oh, man.

Oh, my.

And so, you're listening to a special episode of the Science of Everything podcast on brain preservation and the abolition of death.

0:41.3

I'm your host, James Fodor.

0:43.2

So this episode is an interview that I did with actually a friend of mine, Ariel Zelensnikov Johnson.

0:49.7

I talked with him, his recently published book called The Future Loves You.

0:54.2

So this book is about the idea of how we might abolish death by taking measures to preserve the brain,

1:04.0

or indeed potentially the whole body, of people upon death or just prior to death,

1:09.5

in a way that allows the information that constitutes

1:13.5

their personal identity to be preserved and then potentially used to reconstruct them as a

1:20.1

simulation or potentially through other means at some point in the future. So in the interview,

1:24.9

we go through some of the science and a bit of the philosophy behind all that and talk about the details. So it's quite an interesting episode. So very thought-provoking as well. So hopefully there'll be something of interest to you here. So without further ado, let's get started with the interview. I'm a neuroscientist like James. I'm a research fellow at Monash University, where in my day job, I do neuroscience

of consciousness. So trying to understand the relationship between brains and subjective experiences

1:52.0

and colors and all that. But I'm also very interested in the history and future of scientific

2:00.3

and medical technology. Specifically, I've always been

2:04.0

fascinated by how we've gone from a world where we had essentially no medicine, maybe some herbs,

2:10.3

maybe primitive things like amputations for infected limbs to a world today where we have,

2:19.9

you know, imperfect medicine, but a lot more treatments compared to what existed centuries ago. And also I'm also quite curious about what's

2:24.9

going to happen in the future, like what sort of medical and scientific developments will

2:29.1

we see in 10 years, 20 years, 40 years, 100 years from now. As part of that, and probably like many of you listening, I've always been very interested in

2:37.9

science fiction.

2:39.6

And among that, sort of ideas around, would it be possible to ever have some sort of way
