J.A.R.V.I.S. did nothing to dispute Tony calling him a UI when he was "standing" right in front of him, to correct him to Dr. Banner.
Why would he? Intelligence doesn't require egotism. And he may have underestimated his own abilities as much as Tony did.
His data schematic is tiny and highly artificial compared to Ultron
Yes.
Compared to Ultron. My point all along is that sentience is a spectrum, not a binary on/off question. Obviously JARVIS is less intelligent than a human, but a human is less intelligent than Ultron. Are humans nonsentient just because they're less advanced than Ultron? If not, then why must JARVIS be nonsentient just because he's less advanced than humans? Again, it's rather self-denigrating to assume that human intelligence is the lowest possible level of intelligence in the universe.
Dr. Banner even says "thinking" just looking at it, making no such observation of the other program.
The assertions of characters are only probative about their beliefs, not objective facts. If Tony underestimated JARVIS's sentience, Bruce may have as well. After all, the whole reason we're having this debate is because intelligence is a poorly understood phenomenon. We don't actually know how to define it or differentiate it from the alternative, and a lot of our assumptions about its definition and nature have been called into question. It's still a question that's open for debate and disagreement among scientists. So even the inventors of an AI might not recognize strong AI when they see it.
He's just a very impressive chatbot that can organise and activate certain functions that Tony likely had to arrange for him to control parts of Stark Enterprises. We've seen nothing in the series to show that he is alive and several key scenes in AoU that point out that he isn't.
I will never understand why people insist on the sloppy practice of equating "alive" with "sentient." Plants are alive. Bacteria are alive. Life and consciousness are entirely separate questions. And I'm not talking about any oogy-boogy rubbish about some mystical spark of life. I'm talking about the scientific understanding of cognition and the fact that it's increasingly understood to be a more gradual spectrum than we used to assume.
And I've explained my reasons for thinking that JARVIS must be more self-aware than even the filmmakers probably realized. JARVIS displays empathy. He makes uninvited suggestions and acts on his own initiative. He understands humor. He can read subtext. In
Iron Man 3 there are at least two points where Tony says "You know what to do" or "Is it that time?" and JARVIS is able to understand what action he's requesting. That ability to extract meaning from nonverbal cues and context is something that even autistic humans generally can't do.
If so, all 4 of them are alive, and F.R.I.D.A.Y. along with the two more obscured disc/chips on the desk have been held in digital slavery for years?
Again, I'm not saying "alive" or "human." You're confusing the issue with this sentimental, sloppy terminology. I'm talking about the science of cognition and the fact that the difference between animal and human intelligence is probably more a matter of proportion and organization than one of the absolute presence or absence of a single monolithic property, and thus it stands to reason that the same may apply to strong AI, with a gradual transition from non-awareness to full sapience with multiple intermediate layers of cognitive sophistication and awareness. I'm not trying to draw some absolute line between sapience and nonsapience; I'm trying to say that there is no such line, that it's a continuum instead. It's like trying to define the exact moment when a child becomes an adult. There's a whole transitional process between the two, and different individuals are at different points along that continuum.
As for whether FRIDAY and the others possess the same degree of cognition as JARVIS, it would be reckless to jump to that conclusion without observing them individually. It may be that JARVIS has been able to develop more self-awareness through more extensive use, like
Voyager's Emergency Medical Hologram vs. other EMHs. Again, intelligence isn't a matter of a switch being flipped to the on position, but a matter of a wide range of cognitive processes achieving a harmonious interaction. A newborn human brain needs several years of activity and experience to organize itself into a state allowing it to speak, reason, understand, make plans, etc. We are born with the potential for intelligence, but potential needs to be developed to become actuality.
And really, F.R.I.D.A.Y. is immediately as developed a personality as J.A.R.V.I.S. out of the box
She gives that superficial impression, but again, it would be unscientific to presume that without further study. As I've tried to explain, my reasons for judging JARVIS as partially sapient have to do with specific cognitive abilities he's demonstrated, not merely with the surface appearance of personality.
, so either she's been given portions of his data schematic which further implies they aren't individuals,
Why in the world would you think it implies that? All human brains have the same basic structure determined by genetics, but it's the variations within that shared structure that make us individuals.
