If that's the case, then there are whole vast ares of potential human-mind-space that you or your decedents would never move into or through because of their values, while EM derived from another human might.
We seem to keep trading vague statements about our intuitions back and forth, so let me try to get us a bit more concrete, and maybe that will help us move past that.
For convenient reference, call D the subset of mind-space that I and my descendents can potentially move through or into, and H the subset of mind-space that some human can potentially move through or into.
I completely agree that H is larger than D.
What's your estimate of H/D?
My intuitive sense is that it's <2.
it should be much faster to make an exact copy of you then to make a "child" EM and raise it to adulthood. And if you are the type of person who wants to make lots of copies of yourself, then all those copies will also want to make lots of copies
Even if I grant all of that, it still seems that what's necessary (supposing there's a resource limit here) is to limit the number of people I create, not to prevent me from making clones. If I want to take my allotment of creatable people and spend it on creating clones rather than creating "children," how does that affect you, as long as that allotment is set sensibly? Conversely, if I overflow that allotment with "children", how does that affect you less than if I'd overflowed it with clones?
Put differently: once we effectively restrict the growth rate, we no longer have to be concerned with which factors would have been correlated with higher growth rate had we not restricted it.
What's your estimate of H/D? My intuitive sense is that it's <2.
I would think it's far higher then that. Probably H/D>100, and it might be far higher then that. I tend to think that maintaining some continuity of identity would be very important to uploaded minds (because, honestly, isn't that the whole point of uploading your mind instead of just emulating a random human-like mind?). I also tend to think that there are vast categorizes of experiences that you would not put yourself through just so you could be the kind of person who had been...
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.
