From correspondence between a friend and the Singularitarians, on the question of life, non-life and Deutsch’s Computation reductionism
“If we cannot really know [if machines are alive], then we can’t assume that they aren’t alive any more easily than we can assume they are sentient. But how can we act without assumption of one or the other and still proceed?”
The burden of proof here is on the machines, you could say, and it should be a high burden. I’ve seen no evidence of humans having created any kind of mechanical life, let alone mechanical life having the potential to become superhuman in intelligence. It could be that we can’t do that, that all we can ever do is create really fast machines with a lot of memory, and maybe that’s fine, maybe that’s better.
“If you don’t know if [Shrodinger’s] cat is dead or alive, it seems to me you still have limited options as to how you can proceed. What is better – to assume that it’s more likely the cat is dead and light the box on fire, or to assume it’s more likely alive and open the box so you can at least check before doing something destructive?”
“The question comes down to one of greater harm – which has more dire consequences not just for humans, but for all life? That we assume machines are incapable of reaching a sentient status and continuing to treat them like machines (in other words, assume they can’t possibly be slaves, potentially enslaving something sentient) or to assume that they could be sentient and do everything in our power to figure it out before we get to the point of doing something destructive?”
For all of that, of course I think we should monitor it closely and not do anything avoidable that is destructive. But why would we want to create machines that are alive, let alone a synthetic superintelligence?

I also don’t accept the “Universality of Computation.”
Sorry. I don’t think everything can be reduced to calculation, information retrieval, processing. I do think there is a qualitative difference, further, between life and non-life (which would be “racist” as the author says, though he never says that something “racist” is therefore “not true”; I suppose we are all simply supposed to know this, since “racist” things are, by definition, “bad” and “bad” things can not be “true”.)
Nonsense.
A machine that fools you into thinking it’s not a machine is still a machine. You’ve just been fooled. The Turing test, for all of Turing’s obvious genius and accomplishments, is silly; more importantly, it’s epistemic, not physical/ontologic (it is a statement about conclusions we as humans have come to about the identity of a thing, our knowledge, or seeming knowledge, of that identity, not the identity itself.)
You can say whatever you’d like, but thinking something is alive or human or conscious or whatever does not make it so. I suppose it is fairer to say we simply cannot know, ultimately, whether something is alive in the same way that we are ourselves alive (conscious, sentient, however you’d like to describe it); saying, because we cannot really know, and the thing seems to be alive (sentient, conscious whatever) therefore it is, or may as well be, strikes me as wrong.
(Similarly, you may not know whether or not the cat in the box is dead or alive, but it is either dead or alive, not both, or neither; you simply don’t know. That is to say, it has properties in itself independent of your understanding or observation. A person is alive, sentient, intelligent, conscious, however you want to describe it in himself, not because you think he is.)
I simply do not accept the reductionist idea that life is just non-life that can compute and act with apparent volition, and that the only difference between a person and a software program is computing power and clever enough coding. (I also think it a monstrous idea; but that’s a moral/aesthetic judgment, not an argument against the validity of the concept, so I’ll leave it be).
What is it that drives your computations? (what makes a person want to go left rather than right, decide to write an essay rather than go skiing, etc.) Only living things have desire (as one of their characteristics), volition, drive; these things cannot be reduced to the product of “computation” however complex; they are qualitatively different from that.
Life is not just problem solving (something makes the living creature [not “entity;” a cat or a person is not a rock, a corporation or an iPad] decide to solve or attempt to solve one problem and not some other problem, experience something, abandon something else, etc.
