There's another layer to this as well, I think. Any social media feed interlaces horrible things with wonderful things in a completely contextually devoid list. A funny cat picture and a traumatic picture or video of violence are both "rated" in the same way, with the same imaginary internet points, without any differentiation between good and bad.
I feel like this is also cooking our brains a bit.

"What’s clear is that when we share music — whether at backyard barbecues, holiday gatherings, or road trips with the radio blaring — we’re doing something deeply meaningful. Our brains are literally synchronizing, creating shared neural patterns across generations and differences. In those moments when everyone finds themselves humming the same chorus or tapping to the same beat, we’re experiencing one of life’s simplest yet most profound connections."

Invariant inter-subject relational structures in high order human visual cortex #neuroscience

Invariant inter-subject relational structures in high order human visual cortex - Nature Communications
The neuronal coding principles that underlie inter-individual perceptual similarities remains unclear. Here, the authors compared the stability of relational similarity versus activation patterns across brains and found that relational similarity was preferentially consistent across individuals, potentially underlying shared inter-subject perception.

Octopuses possess a radically decentralized nervous system,
with the majority of their neurons residing in their arms.

From another perspective, we can say it is nine organisms housed within a single skin.
How can multiple humans come to inhabit a single organism with distributed sensory and decision-making capabilities?
How is cognition located in the network that spans bodies and environments?

The brain-body-environment framework studies adaptive be- havior through embodied and situated agents, emphasizing interactions between brains, biomechanics, and environmen- tal dynamics. However, many models often treat the brain as a network of coupled ordinary differential equations (ODEs), neglecting finer spatial properties which can not only increase model complexity but also constrain observable neural dy- namics.

Toward a Physics of Deep Learning and Brains
Deep neural networks and brains both learn and share superficial similarities: processing nodes are likened to neurons and adjustable weights are likened to modifiable synapses. But can a unified theoretical framework be found to underlie them both? Here we show that the equations used to describe neuronal avalanches in living brains can also be applied to cascades of activity in deep neural networks. These equations are derived from non-equilibrium statistical physics and show that deep neural…

Strangers whose brains respond alike to movie clips often become friends later, study finds
People often bond with strangers over the books they read or the movies they watch and build friendships that last. Scientists may now have some insight into why this happens. A study published in Nature Human Behaviour found that participants who responded similarly to the same movie clips even before meeting were more likely to become friends later.

I suspect we’re doing something similar to the tank classifier when we ascribe intelligence to AIs: there are patterns such as (for example) grammatical correctness which we •associate• with this abstract thing called “intelligence,” and we thus mis-infer the existence of everything else we associate with the notion of “intelligence” when we see (for example) correct grammar.
Or should we just call the machine intelligent because we classify it as intelligence because our brains, which we assume are intelligent, think it fits the pattern of intelligence? And now you see what the OP means about “begging the question of intelligence.”

Because they're not physical they don't exist.
