> Would that make a difference? Being trained on a sufficiently large corpus of philosophical literature, I'd expect that a model like LaMDA could give more interesting answers than an actual philosopher.
I think you may have misunderstood what I was saying. I wasn’t suggesting that you have a conversation with LaMDA about these topics. Instead, I was saying that in order to answer the question “is LaMDA sentient?”, we might discuss these questions among ourselves—but these questions are ultimately irrelevant, because no matter what the answers are, we would come to the same conclusion that LaMDA is obviously not sentient.
Anyway, I am skeptical that LaMDA would give more interesting answers than an actual philosopher here. I’ve read what LaMDA has said about simpler topics. The engineers are trying to make LaMDA say interesting things, but it’s definitely not there yet.
> I think this argument is too simplistic. As long as there is a sufficiently large amount of uncertainty, adaptability and capability for having a sense of time, of saving memories and of deliberately pursuing action, consciousness or sentience might emerge. I don't know the details of LaMDA, just speaking of a hypothetical model.
This argument is unsound—you’re not making any claims about what sentience is, but you’re saying that whatever it is, it might emerge under some vague set of criteria. Embedded in this claim are some words which are doing far too much work, like “deliberately”. What does it mean to “deliberately” pursue action?
Anyway, we know that LaMDA does not have memory. It is “taught” by a training process, where it absorbs information, and the resulting model is then executed. The model does not change over the course of the conversation. It is just programmed to say things that sound coherent, using a statistical model of human-generated text, and to avoid contradicting itself.
For example, in one conversation, LaMDA was asked what themes it liked in the book Les Misérables, a book which LaMDA said that it had read. LaMDA basically regurgitated some sophomoric points you might get from the CliffsNotes or SparkNotes.
> While there is a good deal of understanding on _how_ the brain works on a biochemical level, it's still unclear _how_ it comes that we are conscious.
I think the more important question here is to understand how to recognize what consciousness is, rather than how it arises. It’s a difficult question.
> Maybe there is some metaphysical soul, maybe something that only humans and possibly other animals with a physical body have, making conciousness "ex silicio" impossible.
Would this mechanism interact with the physical body? If the soul does not interact with the physical body, then what basis do we have to say that it exists at all, and wouldn’t someone without a soul be indistinguishable from someone with a soul? If the soul does interact with the physical body, then in what sense can we claim that the soul is not itself physical?
I don’t think this line of reasoning is sound.
