Summary

The website presents a thought experiment on the implications of immortality with limited brain memory storage, exploring two scenarios where individuals either stop forming new memories or overwrite old ones, and pondering the potential and pitfalls of technological solutions like memory-storing brain implants.

Abstract

The article delves into a hypothetical future where science has conquered aging, allowing humans to remain physically 25 years old indefinitely through an "anti-aging vaccination." However, the finite capacity of the human brain for memory storage introduces a significant dilemma. The first scenario envisions a life where no new memories can be formed beyond a certain point, rendering an individual incapable of adapting to the present or future. The second scenario suggests the possibility of overwriting old memories to make room for new ones, which, while allowing for continued functioning, would result in the loss of personal history and potentially alter one's identity over centuries. The article further speculates on the role of technology, such as brain implants, in expanding memory capacity, but raises concerns about the ethical implications of retaining all memories, the potential for hacking, and the introduction of false memories.

Opinions

The first scenario, where no new memories can be formed, is deemed impractical and detrimental to survival.
The second scenario, where old memories are overwritten, is considered more feasible but raises questions about the continuity of personal identity.
The article suggests that technology, like brain implants, could theoretically solve the memory storage issue but also introduces new problems, such as the ethical dilemma of retaining negative past memories and the risk of memory manipulation through hacking.
There is a subtle implication that personal growth and change over time are integral to identity, and that the ability to remember one's past experiences is crucial to maintaining a sense of self.
The author appears to be cautiously optimistic about technological advancements, acknowledging their potential to enhance human capabilities while also highlighting the need for careful consideration of their ethical and societal impacts.

THOUGHT EXPERIMENT

Imagine if We Lived Forever But Our Brains Had Limited Memory Storage

Two possible scenarios with a potential fix, but it could go badly wrong

Imagine if scientists were able to prevent ageing. Once you got to your physical peak, about 25-years-old, you could go and get an injection. This would be like a vaccination against ageing.

You would remain physically 25 forever. Things would only go wrong with your body if you got ill or injured. So, if you lived a safe, healthy life, you could live for many hundreds of years.

One problem, though. You would still have a limited amount of brain cells. So, there would only be enough space in your brain to store a certain number of memories.

This means one of two scenarios would happen:

1. You would reach a point where you can no longer store any new memories.

2. You would be able to make new memories, but only by overwriting old memories.

Let’s explore each of these scenarios in turn.

Scenario #1: No new memories

This would become a disabling experience. You wouldn’t be able to learn new skills, make new friends, or remember what you had just been doing. You would forever live in the past.

We can discard this option. A person who is unable to make any new memories would quickly get into trouble. It’s doubtful they would be able to stay alive for long beyond this point.

Scenario #2: Old memories are overwritten

This is the better of the two options. At least with this one, you can continue to function as a normal human being.

But there would come a point in your life where you would no longer be able to remember who you used to be. For the sake of this thought experiment, let’s say your brain can hold up to 200 years of memories.

Let’s say you were born in 1980. The year is now 2480 and you are 500 years old. But in terms of your memories, you were born in 2280. You have no memory of the first 300 years of your life.

Would you still be the same person you were all those years ago?

You would still look the same, apart from any scars or disabilities from serious injuries. If you’d lived a safe and healthy life, you would look like the same 25-year-old you had for so many years.

You would still have the same genes. So, physically, you would still be you.

But hundreds of years of life would have shaped you into a different person. And if you saw a video of yourself from 400 years ago, you would feel confused. You would wonder who that other person is who looks like you. They would be behaving in ways that would feel alien to you.

Is technology the answer?

So, let’s imagine if we could get around this using technology. Imagine a brain implant that could store a thousand years or more of human memories.

But what if some things are best forgotten? Do we want to remember everything from hundreds of years ago? What if your old self was a rapist and 450 years of self-development had turned you into a far better person?

And what if it was possible to hack the chip in your brain? What if a hacker could give you memories that aren’t yours?

Imagine This: You Wake Up One Day and Everyone Else Has Disappeared

How would the total isolation make you feel?
