I can't imagine any mind would intentionally do that to themselves just to explore more sections of mind-space.
Mm. That's interesting. While I can't imagine actually arranging for my child to die in order to explore that experience, I can easily imagine going through that experience (e.g., with some kind of simulated person) if I thought I had a reasonable chance of learning something worthwhile in the process, if I were living in a post-scarcity kind of environment.
I can similarly easily imagine myself temporarily adopting various forms of theism, atheism, former-theism, and all kinds of other mental states.
And I can even more easily imagine encouraging clones of myself to do so, or choosing to do so when there's a community of clones of myself already exploring other available paths. Why choose a path that's already being explored by someone else?
It sounds like we're both engaging in mind projection here... you can't imagine a mind being willing to choose these sorts of many-sigmas-out experiences, so you assume a population of clone-minds would stick pretty close to a norm; I can easily imagine a mind choosing them, so I assume a population of clone-minds would cover most of the available space.
And it may well be that you're more correct about what clones of an arbitrarily chosen mind would be like... that is, I may just be an aberrant data point.
I can easily imagine a mind choosing them, so I assume a population of clone-minds would cover most of the available space.
Ok, so let's say for the sake of arguments that you're more flexible about such things then 90% of the population is. If so, would you be willing to modify yourself into someone less flexible, into someone who never would want to change himself? If you don't, then you've just locked yourself out of about 90% of all possible mindspace on that one issue alone. However, if you do, then you're probably stuck in that state for good; the new you probably wouldn't want to change back.
At some point in the future we may be able to scan someone's brain at very high resolution and "run" them on a computer. [1] When I first heard this as a teenager I thought it was interesting but not hugely important. Running people faster or slower and keeping backups came immediately to mind, and Wikipedia adds space travel, but those three by themselves don't seem like they change that much. Thinking speed doesn't seem to be major limiting factor in coming up with good ideas, we generally only restore from backups in cases of rare failure, and while space travel would dramatically affect the ability of humans to spread [2] it doesn't sound like it changes the conditions of life.
This actually undersells emulation by quite a lot. For example "backups" let you repeatedly run the same copy of a person on different information. You can find identify a person when they're at their intellectual or creative best, and give them an hour to think about a new situation. Add in potentially increased simulation speed and parallelism, and you could run lots of these ones looking into all sorts of candidate approaches to problems.
With emulations you can get around the mental overhead of keeping all your assumptions about a direction of thought in your mind at once. I might not know if X is true, and spend a while thinking about what should happen if it's true and another while about what if it's not, but it's hard for me to get past the problem that I'm still uncertain about X. With an emulation that you can reset to a saved state however, you could have multiple runs where you give some emulations a strong assurance that X is true and some a strong assurance that X is false
You can also run randomized controlled trials where the experimental group and the control group are the same person. This should hugely bring down experimental cost and noise, allowing us to make major and rapid progress in discovering what works in education, motivation, and productivity.
(Backups stop being about error recovery and fundamentally change the way an emulation is useful.)
These ideas aren't new here [3] but I don't see them often in discussions of the impact of emulating people. I also suspect there are many more creative ways of using emulation; what else could you do with it?
[1] I think this is a long way off but don't see any reasons why it wouldn't be possible.
[2] Which has a big effect on estimates of the number of future people.
[3] I think most of these ideas fo back to Carl Schulman's 2010 Whole Brain Emulation and the Evolution of Superorganisms.
