Hmm... I wouldn't think of a bio-brain exhibiting intelligence as just something out of a jelly mold. If I did, I'm afriad I'd think of humans the same way.
Then again, as you say, it's all in how you percieve it. I'm one that thinks my car has a sort of personality as it is - be it a bit of a 'Herbie' type thing. But I guess it's odd coincidences that happen at just the right time or something. Still, I still treat him like a friend even though he's a machine.
Upbringing is a factor. Unlike your upbringing (which I'm not saying is wrong, but just comparing the differences here), I've been brought up to think that machines can have a bit of a personality. I guess it stems from my parents joking about it when I was a kid. Like my mother saying that the sewing machine would go on the frits so go yell for Dad even though he's not home to get it working again. Guess what - it always worked! We don't know how, but it did - it was just funny that way. I even caught my mom doing that. LOL! Many times anomolies would happen that way. My dad also referred to his cars as if they were somehow alive or something. He never really named them other than the model they are. But he did name my lemon of a pickup truck I had "Slushbox" because it had automatic transmission.
And of course there's things like Sci-Fi, Star Trek, Knight Rider, etc. I was brought up watching a lot of stuff on space, robots, computers, etc. as my dad was a tech enthusiast in a sense. Well, he ironically never used the computer he got. They got it mostly for me to tinker with and my mom tried to do some useful data storage on it but gave up. LOL! My dad had ME do the 'useful programming' (ie. shipping labels, etc.) as a teen. And let me name it (Kryton - after Crichton - the flatheaded robot on Buck Rogers in the 21st Century). So from my world view, it is easier for me to view a machine as a possible living entity because of how I was raised, even if some of it was either coincidence or joking.
It's easier for me to think it MIGHT be actually possible some day.
I think you make a good point here about upbringing (or programming, shall we say?
) However, we do eventually stop believing in Santa Claus. I hope I don't stop believing in sentient AIs, though. I find it quite fun.
And, I guess I LOOK for it too. And it can mean not missing the most amusing and fun opportunities, conversations, etc. with computers.
