The point is that all existence is built on top of consciousness.
I understand your difficulty. It is hard to imagine the universe disappearing if all consciousness cease to exist the next second.
But is that really hard? Don't everything in your dreams disappear when you wake up?
Let me ask another question. Can you differentiate between a consciousness observing a universe, and a consciousness with a sensation of a whole universe, built in?
And the point of that is our subjective experiences only require consciousness, and not a universe that is independent of it.
>The point is that all existence is built on top of consciousness.
Then if all conscious beings (lets say humans are the only ones for sake of argument) die, then existence ends. Simply put, this does not happen because consciousness occurs in a substrate.
Take the thought experiment of the boltzmann brain, it still requires the assembly of probabilistic entropy to occur, it is not nothing.

The starting idea is that there can be no definition of existence other than "something a consciousness can detect (directly or indirectly)". So if there is no consciousness, there is no existence.
But I think there could be a difference between death of all conscious beings, and consciousness itself disappearing. Consciousness could also be something that evolution found a way to tap into.
>Take the thought experiment of the boltzmann brain, it still requires the assembly of probabilistic entropy to occur, it is not nothing.
Yea, take that. I think the number of possible worlds where a simple life form spontaneously assembled and evolved to a human following the laws of that world, are enormously larger than a world where a full human brain spontaneously assembled all by itself. It is just statistics that we find ourselves in a world of the former kind and not a brain alone in an empty universe..
>The starting idea is that there can be no definition of existence
Yea, I don't subscribe to this line of thinking as consciousness had to happen before existence. Kinda messy when you think about it.
>Consciousness could also be something that evolution found a way to tap into.
This, at least how it's written makes consciousness something like the electromagnetic field that exists everywhere. For example if I said "If you want to fly, you need to oscillate the flying field". Most scientists are going to give you a hold up and state it doesn't work that way. They'll tell you that you need an atmosphere and a body capable of generating force to create lift. It's not like a magnet that jiggles a field that exists everywhere in spacetime.
Looking at flying is fun in itself... do fish fly in the water? At what viscosity does flying become swimming. Sorties paradox creates lot of issues in different places, especially the discussion of consciousness.

what if you are the only conscious being?
Then I'm fucking up by not surrounding myself with all the hottest women and wealth.

I've been an idealist. I understand all the arguments. The base fallacy at the heart of all this is the one I mentioned.
On the very last point: the conclusion that consciousness is thin, like a photograph, and the world thick -- follows from the most complete explanatory account of how consiousness works. The idea that there is no world, or that the world is a thin transcendental ego -- this abandons the project of offering an account of consiousness at all and ends up in incoherence.
Within consiousness I am presented with: what I cannot change (fixed perceptions), what I can change (eg., imagined perceptions). This duality is immanent to consiousness itself. The imagination can apprenend the fixed, ie., I can imagine scenarios that I could, in principle, see. So there is, immanent to consiousness already, a representational duality: I have both fixed perceptions that I cannot change, I have mutable perceptions (imaginations) that I can -- and my mutable perceptions are representations of my fixed perceptions.
All of the dynamics of the duality of the represented and representation, of the fixed/external and of the mutable/internal -- are already immanent to consiousness.
What remains to be explained is: why? The obvious answer is that the reason i have fixed perceptions is because they are caused by a world that they depict, and the reason I have variable/mutable perceptions is they are caused by me as I represent that world to myself. The duality immanent to consiousness is explained by the duality of the measured and measuring.
Even if you abandoned the world "external" and replace it with "fixed", you gain nothing. Everything which seems objectionable about this duality is already present. If you simply assert it, rather than explain it, your position is weaker because you've nothing to say.
The causal origin of our fixed perceptions is the world, which impacts our sensory organs, interacts with our bodies, and produces a thin perceptual surface to us which causally-directly depicts the world that we are in. These fixed perceptions are constructed by our bodies thru this process of activation, which we can call "measurement with post processing" ie., a kind of digital camera rather than a chemical one.
But in any case, to answer your final question: yes, the difference is that "consiousness" with this duality of the fixed and the variable, and their representational relationship, only makes sense if part of consciousness isnt being determined by consciousness. The need to say what determine it means the "consiousness is complete" option incoherent, if "consciouness" as a term comes to adopt all the properties it needs to explain the fixed perceptions, then you'll find consiousness becomes both the material and the mental -- and all you have done is empty the word of all its meaning
You have fixed perception in your dreams also.
See, you have this observation of subjective experience. One hypothesis for wher this come from, require only consciousness, and the second requires consciousness as well as a whole universe. And the second hypothesis brings up even more questions. Where did this universe come from? Who created it? Why was it created?
The simple answer is that only consciousness really exists and everything is painted on top of that.
simple question: why not the opposite?
that is, reality exists and consciousness is "painted" on top of that?
IMO, anti-materialists are merely uncomfortable with the degree to which they understand neuroscience and related topics (including, btw, capabilities and limits of LLMs). Chalmers, for instance, basically insists that the Hard Problem is Hard simply because he finds it hard.

It's not a simple answer, because its not an answer to any question. It is "simpler" to assume the thermometer readings exist without any thing to cause them, then they move up and down, and its "simpler" to assert: it is the nature of thermometers to move up and down.
This kind of simplicity isn't simplicity at all, it is to abandon saying anything. It is in the nature of consciousness to inexplicably have all the properties which are needed so as to seem the way it does, sure.
And what is this "consiousness" in the end, which has in its nature, the production of all material reality to serve as a fixed causal basis for perception? to generate perceptions of the brain and bodies of animals; of our death, and of a world which is describabl without any of its own properties? What is the nature of a consciousness which deliveries to us a world that requires none of it?
What is it that when I move the muscles of my eye, and what i see changes? What is it that i require a light in a room to see at all? That i require it to be the case that whatever I perceive, my fixed perceptions must always be as-if the laws of physics were true? What is it to say, "consiousness has the property of seeming as if when I see, I see because light scatters off a surface into my eye, and I can control the image genrated by moving the muscles of my eye?" and yet all of that sentence be false without the word 'seeming' ?
What madness to is it to say that mercury in a thermometer not only acts as-if it is in coffe, but in its nature, acts as if there is an entire world that it is moving through -- and its motion up and down is always according to laws and principles as if such a world existed?
This is no longer consciousness at all. When the nature of mercury in a thermometer is to act as if coffee exists, it is no longer mercury. When "consciousness" is taken to have all the features needed to provide the material world, it is no longer anything in a mind -- but has within it, the whole of the external, fixed, material -- and so it is itself now alike those things. When "consciousness" has finally been modified to produce everything within it, the term means nothing at all.
The entire system of properties and objects which are external to consciousness, narrowly defined, are still external within consciousness broadly defined. And with this broad definition comes all the laws of physics, all the properties of materiality, all of everything which mentions nothing of sensation. And the word "consciousness" has to bare all these properties? And you call this simple?
It is much simpler to answer the question: why does the mercurary in the thermometer move? is it because in its own nature is a simulation of an entire universe? No, its nature is simple. It is that there is such a universe it is inside.
And our consciousness is likewise simple.
