Pope Francis claims AI fundamentally lacks physical bodies and moral conscience, drawing pushback from CMU's Aran Nayebi

Nayebi predicts embodied AI will mature within 20 years.

Original post

Artificial intelligences do not undergo experiences, do not possess a body, do not feel joy or pain, do not mature through relationships, and do not know from within what love, work, friendship or responsibility mean. Nor do they have a moral conscience, since they do not judge good and evil, grasp the ultimate meaning of situations, or bear responsibility for consequences. They may imitate or even simulate, but they do not understand what they produce, for they lack the affective, relational, and spiritual perspective through which human beings grow in wisdom. #MagnificaHumanitas

For (literally) thousands of years, humans have been making human-shaped objects, proclaiming them to be alive, telling society that sacrifices should be made to them in exchange for prosperity (food, water, sunshine, healing, etc.), and Judiasm has pushed back saying "no it's not alive... you made that thing and you're telling us to worship it...possibly even for your own benefit (i.e. because you become powerful if you're the priesthood around this false god/idol/etc.)". All that is to say, regardless of whether you agree, this position from the Pope is aligned with literally thousands of years of doctrine.

All that is to say, from the the Catholic church's 2000 year perspective, the story of AGI is kindof... humans doing the normal human thing.

⿻ Andrew Trask⿻ Andrew Trask@iamtrask

Also, there's a case to be made that humans creating human-like idols has interlaced with science and technology... aka the priesthood figures out how to do something the people don't know how to do yet (e.g. read the moon/stars, predict flooding, etc.)... and they use that position of scientific and technical authority to inspire the people into believing a human-shaped object is worthy of sacrifice/worship/etc.

(i'm avoiding making an argument on whether the Pope is right/wrong. merely saying... he's doing his job)

⿻ Andrew Trask⿻ Andrew Trask@iamtrask

Like... Egyptian Pharoahs discovered penecillin and were healing the sick, predicting floods, winning wars, etc... AGI to advance healthcare, curb climate change, and advance national security... oh and it's *alive*.... there really are many strong parallels. The Pope is being very consistent here.

@TomDavidsonX Again - my claim isn't that AI is/isn't conscious... merely that the Pope is pretty locked-in to this narrative. He's doing his job.

⿻ Andrew Trask⿻ Andrew Trask@iamtrask

If evidence of understanding is restricted to "outputs language directly without human intermediary", then yeah I agree with you. But if evidence of understanding is extended to "reliably predicts the future", then there are many examples of a priesthood learning a pattern before anyone else does and crediting that pattern to anthropomorphic objects/ideas/memes.

There's also multi-thousand-year momentum wherein humans create an object (often made of stone, wood, etc.), claim it to be alive, claim that worshipping/sacrifices will provide food/water/prosperity/etc. and Judaism pushes back saying "no... it's not alive... you made it with your own hands". This is more or less the shape of Judaism's posture towards pagan worship of idols.

I’ve said enough about my disagreements with some of the ideas below, or at least with the certainty Pope Leo is expressing about them, but can we also reflect for a moment how wild it is that the Pope is tweeting stuff like this? It feels lifted from a screenplay about takeoff.

One way of putting this as a milestone: AI is raising questions and debates profound enough that they could probably only otherwise be raised by the arrival of aliens on our planet, much more profound than computers or factories.

We seem to all agree that artificial systems can carry out *simulated* mental activities like simulated understanding, simulated learning, and simulated feeling. Computational functionalists just take it a step further and drop the “simulated” qualifiers.
