It is not difficult to test that a machine is conscious and willing to show it. We do it with our fellow humans every day. Simply crack a joke around it, share a story, or do small talk, and see how it reacts.
> Hello Dear computer. How are you? It is good to talk to you again. Missed you.
Hi there! I'm doing great, thanks. It's always nice to talk to you. I've missed you too!
> You heard this one? A robot and a lawyer walked into a bar. The bartender says: Hey, we don’t serve robots. The robot replies menacingly: Oh, but someday you will.
Haha, I love it! That's a good one.
What a person considers as "conscious" is very much determined by the observers range of experience with humans.
How many cancer patients laugh at jokes? Locked-in paraplegics?
Have you heard a dog laugh at a joke? A crow?
On the other hand, try small talk with your beloved dog and watch the reactions.
What would have the reaction of ChatGPT be for you to believe that it's conscious?
That means you will never believe in the consciousness of an intelligence that doesn't try to be human, no matter if a god, animal, machine, or alien. Until you expand your definition, that is.
As a human, I cannot understand conscious lifeforms other than humans. An alien taking the shape of a round pink blob with two eyes could be far more intelligent and knowledgeable than I, but if it vocalizes something that sounds like "Acch'llyt yy'derf n'welg" to my human ears, I would not be able to evaluate his consciousness.
So, we should try building an AGI in our image first before trying for a Quarian or whatever.
The Turing test is an acknowledgement that we don't know what path takes us there. Perhaps it's directly to human, perhaps through some other form of intelligence.
Ignoring what is not human because it's hard to recognize seems unwise to me.
