This is the third post in a series explaining my view that we could be in the most important century of all time. ([Here's the roadmap for this series.](https://www.lesswrong.com/posts/yHzDrTCum4rdNRDJJ/the-most-important-century-sequence-introduction))

*   The [first piece](https://www.lesswrong.com/posts/F5ktR95qqpmGXXmLq/all-possible-views-about-humanity-s-future-are-wild-1) in this series discusses our unusual era, which could be very close to the transition between an Earth-bound civilization and a stable galaxy-wide civilization.
*   This piece discusses "digital people," a category of technology that could be key for this transition (and would have even bigger impacts than the hypothetical [Duplicator](https://www.lesswrong.com/posts/zHYjpEpdCcBbDYHkC/the-duplicator-instant-cloning-would-make-the-world-economy) discussed previously).
*   Many of the ideas here appear somewhere in sci-fi or speculative nonfiction, but I'm not aware of another piece laying out (compactly) the basic idea of digital people and the key reasons that a world of digital people would be so different from today's.
*   The idea of digital people provides a concrete way of imagining how the right kind of technology (which I believe to be almost certainly feasible) could change the world **radically**, such that "humans as we know them" would no longer be the main force.
*   It will be important to have this picture, because I'm going to argue that AI advances this century could quickly lead to digital people or similarly significant technology. The transformative potential of something like digital people, combined with how quickly AI could lead to it, form the case that we could be in the most important century.

**Intro**
---------

[Previously](https://www.lesswrong.com/posts/zHYjpEpdCcBbDYHkC/the-duplicator-instant-cloning-would-make-the-world-economy), I wrote:

*When some people imagine the future, they picture the kind of thing you see in sci-fi films. But these sci-fi futures seem very tame, compared to the future I expect ...*

*The future I picture is enormously bigger, faster, weirder, and either much much better or much much worse compared to today. It's also potentially a lot sooner than sci-fi futures: I think particular, achievable-seeming technologies could get us there quickly.*

This piece is about **digital people**, one example[**^1^**](https://www.lesswrong.com/posts/twEFb7Qz9ZEMZCPdM/digital-people-would-be-an-even-bigger-deal?commentId=jAGyZCoDynHxzf9H2) of a technology that could lead to an extremely big, fast, weird future.

To get the idea of digital people, imagine a computer simulation of a specific person, in a virtual environment. For example, a simulation of you that reacts to all "virtual events" - virtual hunger, virtual weather, a virtual computer with an inbox - just as you would. (Like [The Matrix](https://www.imdb.com/title/tt0133093/)? See footnote.[**^2^**](https://www.lesswrong.com/posts/twEFb7Qz9ZEMZCPdM/digital-people-would-be-an-even-bigger-deal?commentId=MLvKPjPGeGvLLNnwF)) I explain in more depth in the [FAQ companion piece](https://www.lesswrong.com/posts/jDtdjTLMAQLZjPuBn/digital-people-faq).

The central case I'll focus on is that of digital people just like us, perhaps created via [mind uploading](https://en.wikipedia.org/wiki/Mind_uploading) (simulating human brains). However, one could also imagine entities unlike us in many ways, but still properly thought of as "descendants" of humanity; those would be digital people as well. (More on my choice of term [in the FAQ](https://www.lesswrong.com/posts/jDtdjTLMAQLZjPuBn/digital-people-faq).)

Popular culture on this sort of topic tends to focus on the prospect of [digital immortality](https://en.wikipedia.org/wiki/Digital_immortality): people avoiding death by taking on a digital form, which can be backed up just like you back up your data. But I consider this to be small potatoes compared to other potential impacts of digital people, in particular:

*   **Productivity.** Digital people could be copied, just as we can easily make copies of ~any software today. They could also be run much faster than humans. Because of this, digital people could have effects comparable to those of the [Duplicator](https://www.lesswrong.com/posts/zHYjpEpdCcBbDYHkC/the-duplicator-instant-cloning-would-make-the-world-economy), but more so: unprecedented (in history or in sci-fi movies) levels of economic growth and productivity.
*   **Social science.** Today, we see a lot of progress on understanding scientific laws and developing cool new technologies, but not so much progress on understanding human nature and human behavior. Digital people would fundamentally change this dynamic: people could make copies of themselves (including sped-up, temporary copies) to explore how different choices, lifestyles and environments affected them. Comparing copies would be informative in a way that current social science rarely is.
*   **Control of the environment.** Digital people would experience whatever world they (or the controller of their virtual environment) wanted. Assuming digital people had true conscious experience (an assumption discussed [in the FAQ](https://www.lesswrong.com/posts/jDtdjTLMAQLZjPuBn/digital-people-faq)), this could be a good thing (it should be possible to eliminate disease, material poverty and non-consensual violence for digital people) or a bad thing (if human rights are not protected, digital people could be subject to scary levels of control).
*   **Space expansion.** The population of digital people might become staggeringly large, and the computers running them could end up distributed throughout our galaxy and beyond. Digital people could exist anywhere that computers could be run - so space settlements could be more straightforward for digital people than for biological humans.
*   **Lock-in.** In today's world, we're used to the idea that the future is unpredictable and uncontrollable. Political regimes, ideologies, and cultures all come and go (and evolve). But a community, city or nation of digital people could be much more stable.
    *   Digital people need not die or age.
    *   Whoever sets up a "virtual environment" containing a community of digital people could have quite a bit of long-lasting control over what that community is like. For example, they might build in software to reset the community (both the virtual environment and the people in it) to an earlier state if particular things change - such as who's in power, or what religion is dominant.
    *   I consider this a disturbing thought, as it could enable long-lasting authoritarianism, though it could also enable things like permanent protection of particular human rights.

I think these effects (elaborated below) could be a very good or a very bad thing. How the early years with digital people go could irreversibly determine which.

I think similar consequences would arise from any technology that allowed (a) extreme control over our experiences and environment; (b) duplicating human minds. This means there are potentially **many ways for the future to become as wacky as what I sketch out here.** I discuss digital people because doing so provides a particularly easy way to imagine the consequences of (a) and (b): it is essentially about transferring the most important building block of our world (human minds) to a domain (software) where we are used to the idea of having a huge amount of control to program whatever behaviors we want.

Much of this piece is inspired by [Age of Em](https://smile.amazon.com/Age-Em-Work-Robots-Earth/dp/1536619590?sa-no-redirect=1), an unusual and fascinating book. It tries to describe a hypothetical world of digital people (specifically mind uploads) in a lot of detail, but (unlike science fiction) it also aims for predictive accuracy rather than entertainment. In many places I find it overly specific, and overall, I don't expect that the world it describes will end up having much in common with a real digital-people-filled world. However, it has a number of sections that I think illustrate how powerful and radical a technology digital people could be.

Below, I will:

*   Describe the basic idea of digital people, and link to a [FAQ](https://www.lesswrong.com/posts/jDtdjTLMAQLZjPuBn/digital-people-faq) on the idea.
*   Go through the potential implications of digital people, listed above.

**Premises**
------------

This piece focuses on how digital people could change the world. I will mostly assume that **digital people are just like us, except that they can be easily copied, run at different speeds, and embedded in virtual environments.** In particular, I will assume that digital people are conscious, have human rights, and can do most of the things humans can, including interacting with the real world.

I expect **many readers will have trouble engaging with this until they see answers to some more basic questions about digital people.** Therefore, I encourage readers to click on any questions that sound helpful from the [companion FAQ](https://www.lesswrong.com/posts/jDtdjTLMAQLZjPuBn/digital-people-faq), or just read the FAQ straight through.

**How could digital people change the world?**
----------------------------------------------

### **Productivity**

Like any software, digital people could be instantly and accurately copied. [The Duplicator](https://www.lesswrong.com/posts/zHYjpEpdCcBbDYHkC/the-duplicator-instant-cloning-would-make-the-world-economy) argues that the ability to "copy people" could lead to rapidly accelerating economic growth: "Over the last 100 years or so, the economy has doubled in size every few decades. With a Duplicator, it could double in size every year or month, on its way to hitting the limits."

![](https://www.cold-takes.com/content/images/2021/07/digital-people-feedback-loop.gif)

Thanks to María Gutiérrez Rojas for this graphic, a variation on a similar set of graphics from [The Duplicator]( https://www.lesswrong.com/posts/zHYjpEpdCcBbDYHkC/the-duplicator-instant-cloning-would-make-the-world-economy) illustrating how duplicating people could cause explosive growth.

Digital people could create a more dramatic effect than this, because of their ability to be sped up (perhaps by thousands or millions of times)[**^3^**](https://www.lesswrong.com/posts/twEFb7Qz9ZEMZCPdM/digital-people-would-be-an-even-bigger-deal?commentId=PwzPHjkq9mtAgS9yT) as well as slowed down (to save on costs). This could further increase both speed and coordinating ability.[**^4^**](https://www.lesswrong.com/posts/twEFb7Qz9ZEMZCPdM/digital-people-would-be-an-even-bigger-deal?commentId=S5RXn52AK8e9oXRkv)

Another factor that could increase productivity: "Temporary" digital people could complete a task and then retire to a nice virtual life, while running very slowly (and cheaply).[**^5^**](https://www.lesswrong.com/posts/twEFb7Qz9ZEMZCPdM/digital-people-would-be-an-even-bigger-deal?commentId=sDqmzcpwDRbpNpeKb) This could make some digital people comfortable copying themselves for temporary purposes. Digital people could, for example, copy themselves hundreds of times to try different approaches to figuring out a problem or gaining a skill, then keep only the most successful version and make many copies of that version.

It's possible that digital people could be *less* of an economic force than [The Duplicator](https://www.lesswrong.com/posts/zHYjpEpdCcBbDYHkC/the-duplicator-instant-cloning-would-make-the-world-economy) since digital people would lack human bodies. But this seems likely to be only a minor consideration (details in footnote).[**^6^**](https://www.lesswrong.com/posts/twEFb7Qz9ZEMZCPdM/digital-people-would-be-an-even-bigger-deal?commentId=t4YjDrozTjcJPTmvB)

### **Social science**

Today, we see a lot of impressive innovation and progress in some areas, and relatively little in other areas.

For example, we're constantly able to buy cheaper, faster computers and more realistic video games, but we don't seem to be constantly getting better at making friends, falling in love, or finding happiness.[**^7^**](https://www.lesswrong.com/posts/twEFb7Qz9ZEMZCPdM/digital-people-would-be-an-even-bigger-deal?commentId=Rj9PgkX77pKww4cau) We also aren't clearly getting better at things like fighting addiction, and getting ourselves to behave as we (on reflection) want to.

One way of thinking about it is that *natural sciences* (e.g. physics, chemistry, biology) are advancing much more impressively than *social sciences* (e.g. economics, psychology, sociology). Or: "We're making great strides in understanding natural laws, not so much in understanding ourselves."

Digital people could change this. It could address what I see as perhaps the **fundamental reason social science is so hard to learn from: it's too hard to run true experiments and make clean comparisons.**

Today, if we we want to know whether meditation is helpful to people:

*   We can compare people who meditate to people who don't, but there will be lots of differences between those people, and we can't isolate the effect of meditation itself. (Researchers try to do so with various statistical techniques, but these raise their own issues.)
*   We could also try to run an experiment in which people are randomly assigned to meditate or not. But we need a lot of people to participate, all at the same time and under the same conditions, in the hopes that the differences between meditators and non-meditators will statistically "wash out" and we can pick up the effects of meditation. Today, these kinds of experiments - known as "randomized controlled trials" - are expensive, logistically challenging, time-consuming, and almost always end up with ambiguous and difficult-to-interpret results.

But in a world with digital people:

*   Anyone could make a copy of themselves to try out meditation, perhaps even dedicating themselves to it for several years (possibly sped-up).[**^8^**](https://www.lesswrong.com/posts/twEFb7Qz9ZEMZCPdM/digital-people-would-be-an-even-bigger-deal?commentId=nn2X8GrMXqAPtKkyp) If they liked the results, they could then meditate for several years themselves, and ensure that all future copies were made from someone who had reaped the benefits of meditation.
*   Social scientists could study people who had tried things like this and look for patterns, which would be much more informative than social science research tends to be now. (They could also run deliberate experiments, recruiting/paying people to make copies of themselves to try different lifestyles, cities, schools, etc. - these could be much smaller, cheaper, *and* more definitive than today's social science experiments.[**^9^**](https://www.lesswrong.com/posts/twEFb7Qz9ZEMZCPdM/digital-people-would-be-an-even-bigger-deal?commentId=FoZQtRwH2NFumon9W))

The ability to run experiments could be good or bad, depending on the robustness and enforcement of scientific ethics. If informed consent weren't sufficiently protected, digital people could open up the potential for an enormous amount of abuse; if it were, it could hopefully primarily enable learning.

Digital people could also enable:

*   **Overcoming bias.** Digital people could make copies of themselves (including temporary, sped-up copies) to consider arguments delivered in different ways, by different people, including with different apparent race and gender, and see whether the copies came to different conclusions. In this way they could explore which cognitive biases - from sexism and racism to wishful thinking and ego - affected their judgments, and work on improving and adapting to these biases. (Even if people weren't excited to do this, they might have to, as others would be able to ask for information on how biased they are and expect to get clear data.)
*   **Bonanzas of reflection and discussion.** Digital people could make copies of themselves (including sped-up, temporary copies) to study and discuss particular philosophy questions, psychology questions, etc. in depth, and then summarize their findings to the original.[**^10^**](https://www.lesswrong.com/posts/twEFb7Qz9ZEMZCPdM/digital-people-would-be-an-even-bigger-deal?commentId=uibDS8vjCg7CSDzce) By seeing how different copies with different expertises and life experiences formed different opinions, they could have much more thoughtful, informed answers than I do to questions like "What do I want in life?", "Why do I want it?", "How can I be a person I'm proud of being?", etc.

### **Virtual reality and control of the environment**

As stated above, digital people could live in "virtual environments." In order to design a virtual environment, programmers would systematically generate the right sort of light signals, sound signals, etc. to send to a digital person as if they were "really there."

One could say the historical role of science and technology is to give people more control over their environment. And one could think of digital people almost as the logical endpoint of this: digital people would experience whatever world they (or the controller of their virtual environment) wanted.

This could be a very bad or good thing:

![](https://www.cold-takes.com/content/images/2021/06/matrix-bad-squarer.png)

**Bad thing.** Someone who controlled a digital person's virtual environment could have almost unlimited control over them.

*   For this reason, it would be important for a world of digital people to include effective enforcement of basic human rights for all digital people. (More on this idea [in the FAQ](https://www.lesswrong.com/posts/jDtdjTLMAQLZjPuBn/digital-people-faq).)
*   A world of digital people could very quickly get dystopian if digital people didn't have human rights protections. For example, imagine if the rule were "Whoever owns a server can run whatever they want on it, including digital copies of anyone." Then people might make "digital copies" of themselves that they ran experiments on, forced to do work, and even open-sourced, so that anyone running a server could make and abuse copies. [This very short story](https://qntm.org/mmacevedo) (recommended, but chilling) gives a flavor for what that might be like.

![](https://www.cold-takes.com/content/images/2021/06/matrix-good-squarer.gif)

**Good thing.** On the other hand, if a digital person were in control of their own environment (or someone else was and looked out for them), they could be free from any experiences they wanted to be free from, including hunger, violence, disease, other forms of ill health, and debilitating pain of any kind. Broadly, they could be "free from material need" - other than the need for computing resources to be run at all.

*   This is a big change from today's world. Today, if you get cancer, you're going to suffer pain and debilitation even if everyone in the world would prefer that you didn't. Digital people need not experience having cancer if they and others don't want this to happen.
*   In particular, physical coercion within a virtual environment could be made impossible (it could simply be impossible to transmit signals to another digital person corresponding to e.g. being punched or shot).
*   Digital people might also have the ability to experience a lot of things we can't experience now - inhabiting another person's body, going to outer space, being in a "dangerous" situation without actually being in danger, eating without worrying about health consequences, changing from one apparent race or gender to another, etc.

### **Space expansion**

If digital people underwent an explosion of economic growth as discussed above, this could come with an explosion in the *population* of digital people (for reasons discussed in [The Duplicator](https://www.lesswrong.com/posts/zHYjpEpdCcBbDYHkC/the-duplicator-instant-cloning-would-make-the-world-economy)).

It might reach the point where they needed to build spaceships and leave the solar system in order to get enough energy, metal, etc. to build more computers and enable more lives to exist.

Settling space could be much easier for digital people than for biological humans. They could exist anywhere one could run computers, and the basic ingredients needed to do that - raw materials, energy, and "real estate"[**^11^**](https://www.lesswrong.com/posts/twEFb7Qz9ZEMZCPdM/digital-people-would-be-an-even-bigger-deal?commentId=6bjQQPnrmkeHcBxDp) \- are all super-abundant throughout our galaxy, not just on Earth. Because of this, the population of digital people could end up becoming staggeringly large.[**^12^**](https://www.lesswrong.com/posts/twEFb7Qz9ZEMZCPdM/digital-people-would-be-an-even-bigger-deal?commentId=wBXwJLgtDhjhEpset)

### **Lock-in**

In today's world, we're used to the idea that the future is unpredictable and uncontrollable. Political regimes, ideologies, and cultures all come and go (and evolve). Some are good, and some are bad, but it generally doesn't seem as though anything will last forever. But communities, cities, and nations of digital people could be much more stable.

First, because digital people need not die or physically age, and their environment need not deteriorate or run out of anything. As long as they could keep their server running, everything in their virtual environment would be physically capable of staying as it is.

Second, because an environment could be designed to *enforce* stability. For example, imagine that:

*   A community of digital people forms its own government (this would require either overpowering or getting consent from their original government).
*   The government turns authoritarian and repeals the basic human rights protections discussed [in the FAQ](https://www.lesswrong.com/posts/jDtdjTLMAQLZjPuBn/digital-people-faq).
*   The head wants to make sure that they - or perhaps their ideology of choice - stays in power forever.
*   They could overhaul the virtual environment that they and all of the other citizens are in (by gaining access to the source code and reprogramming it, or operating robots that physically alter the server), so that certain things about the environment can never be changed - such as who's in power. If such a thing were about to change, the virtual environment could simply prohibit the action or reset to an earlier state.
*   It would still be possible to change the virtual environment from outside - e.g., to physically destroy, hack or otherwise alter the server running it. But if this were taking place after a long period of population growth and space colonization, then the server might be way out in outer space, light-years from anyone who'd be interested in doing such a thing.

Alternatively, "digital correction" could be a force for good if used wisely enough. It could be used to ensure that no dictator ever gains power, or that certain basic human rights are always protected. If a civilization became "mature" enough - e.g., fair, equitable and prosperous, with a commitment to freedom and self-determination and a universally thriving population - it could keep these properties for a very long time.

(I'm not aware of many in-depth analyses of the "lock-in" idea, but [here are some informal notes](https://jessriedel.com/index_files/Value%20Lock-in%20Notes%202021%20(Public%20version).pdf) from physicist [Jess Riedel](https://jessriedel.com/).)

### **Would these impacts be a good or bad thing?**

Throughout this piece, I imagine many readers have been thinking "That sounds terrible! Does the author think it would be good?" Or "That sounds great! Does the author disagree?"

My take on a future with digital people is that it **could be very good or very bad, and how it gets set up in the first place could irreversibly determine which.**

*   Hasty use of lock-in (discussed [above](https://www.lesswrong.com/posts/twEFb7Qz9ZEMZCPdM#Lock_in)) and/or overly quick spreading out through the galaxy (discussed [above](https://www.lesswrong.com/posts/twEFb7Qz9ZEMZCPdM#Space_expansion)) could result in a huge world full of digital people (as conscious as we are) that is heavily dysfunctional, dystopian or at least falling short of its potential.
*   But acceptably good initial conditions (protecting basic human rights for digital people, at a minimum), plus a lot of patience and accumulation of wisdom and self-awareness we don't have today (perhaps facilitated by [better social science](https://www.lesswrong.com/posts/twEFb7Qz9ZEMZCPdM#Social_science)), could lead to a large, stable, much better world. It should be possible to eliminate disease, material poverty and non-consensual violence, and create a society much better than today's.
