I don't understand from their research if
1) The the blood flow is following the computational/metabolic demand (via the endothelial cells communicating via gap junctions)
2) the brain is signaling the endothelial cells directly.
Maybe the paper explains it, or maybe more research required.
On the negative side, I definitely have a harder time reaching my maximum pulse when working out.

There is an "Objective Reality" (mutable, evolves into many forms and includes both material/non-material concepts) and a "Witness-Consciousness" (immutable and attributeless). The latter is embodied in one form of the former which we call Sentient Living Beings. But we forget the distinction between the two and experience reality through its own subjective evolutes within the embodied being i.e. Sensory Mind, Intelligence and Ego. Various techniques/practices have been prescribed in Samkhya/Yoga/etc. to break out of this illusion and realize that one is simply pure awareness/consciousness beyond any experience. This is what is called as Kaivalya/Moksa/Nirvana i.e. a state of mind in which there is total freedom from everything to do with objective reality.

Because the Essence that is the arrangement of molecules replicates onto other molecules, and it is more effective at replicating when it dedicates some of it's molecules to perceive and model it's own existence, in order to run experiments on it. That way it's more likely to find a behavior for the rest of the molecules to successfully replicate. So the molecules experience themselves, and the experience becomes more intense the more advanced the experiments are that can be run on the model.

It's not true that we have to be conscious - we can do things on autopilot too. The same way we can be thoughtless in treating others - we can turn the machinery off.

Recently I was thinking of a very hard problem and I cannot absolutelly recollect approx 30 minutes of the drive home. Apparently my body and some part of the brain took over the driving, while my cortex was busy with the problem reserving the short term memory completly. I snapped out of the situation when apparently a stronger break was needed, and this intrerupted my flow and popped my attention to the road. Fascinating!

That part of the brain is the cerebellum (mostly).

I do feel like most forms of leisure - watching / playing something, alcohol / drugs, sleeping - are basically this, you lose some of your consciousness and awareness in favor of what you're focusing on, or floating / free associating.

That's a weird use of the term. Doesn't match how I would define it, but you do you.

I think it's a bit kooky, but there are weirder things that are true in this little Universe.

I’m sure at some cosmic level there’s cities of marbles like ours just humming away.

Humans believing that they are special is as old as human history goes. Special as a species, but many groups also consider themselves special, and individuals as well. Seems to be an emergent thing from the human psyche. One that has had terrible consquences over the millenia, but I might be overlooking the upsides.

But I should mention this PoV only works from an “all humans are equal” angle.

I was replying to the person who suggested the universe might be consciously exploring itself (goal) via an arrangement of molecules into humans. For fun, maybe the arranging process is at the beginning and the end goal is some kind of cosmic party after which everything resets again, or something.

The former could be applied to whatever LLM is the hype of the day.
It's interesting though that the only consciousness that I'm sure of exists is my own. Anybody else's is just somehing I'm assuming. You can measure intelligence, but not consciousness.

Persons with damaged brains have damaged consciousness. Persons with underdeveloped brains have underdeveloped consciousness. People without functioning brains have no detectable consciousness.
There is a metric ton of observed and collected data on consciousness.
Of course evidence does not equal proof…

-Bill Hicks Don't take this as downplaying at all, because it's a fantastic and uplifting revelation, so long as one doesn't presume they're the first to consider it (it is even better this way imo)
