It is not just a machine it is the infinite machine responsible for the universe but for at least two reasons not dependent on it. Given the nature of the universe we can argue that a high level of sophistication and intricacy could be expected from it. Firstly in terms of computation.
You could argue, and it has been done, this is just a rehash of the Intelligent Design argument. We have no idea how many universes might or might not have emerged from an infinite reality, we have no reason to presume that ours is in any way special in a broader sense, or to presume that it's anything more than the unguided, incidental ongoing reaction to entirely undirected forces.
On the other hand although there are no logical barriers to how intricate this machine could be and that the choice of a non intelligent machine by you is an arbitrary one.
I'm not saying that it's not possible, I'm just arguing that it's not necessary. The choice is not an arbitrary one, it's an application of Ockham's Razor in the absence of any concrete information; complexity sufficient to manifest consciousness is, in all the examples we're aware of, in excess of the complexity required for undirected natural reactions.
It has other properties as the ultimate thing which I believe render it unlike any unconscious thing in our experience.
Such as?
But we don't know what is necessary to produce and sustain a universe.
No, we don't, we are positing possibilities, not determining truth.
In fact, it is likely that it needs to be highly sophisticated.
Why? The entirety of the universe, so far as we can tell, depends on the interaction of four simple forces, yet it produces everything from the Big Bang to the heat death of the universe, from Brisbane to Harry Potter, from Betelguese to Hemel Hempstead... why does the extra-universal reality need to be sophisticated?
A mechanistic intelligence fulfils so much here if only in terms of computation.
You only need computation though, in order to explain this particular existence if you are presuming that we were in some way intended or the point - if we are another sequence of eddies in the currents of energy moving through reality, if you do not presume any external significance to our existence, then you do not need any complex computation.
It goes no further than being a mechanistic reality.
It goes significantly beyond it, because it introduce intent, it presumes significance to certain things for which we do not have any reason.
It has the beauty of fulfilling what people have been trying to explain to Alan over countless posts....intelligence and consciousness are mechanistic realities.
That they are does mean that each and every instance of mechanistic behaviour must exhibit them, though.
We don't actually know that, the limits you are placing are not warranted by logic and are arbitrary. Mechanistic reality is not being exceeded.
I'm not limiting possibilities, I'm simply limiting my presumptions to what might be considered necessary.
That is just one line of speculation though based around the ultimate, infinite machine though. It is debateable whether it acts by chance since a) that would make it not ultimate and b) we would be introducing an entity(chance) beyond necessity against Occam's razor.
It doesn't operate by chance, it operates by strict mechanical physical laws, but there is no reason to presume it does so with any particular direction. I fail to see how that doesn't make it 'ultimate'.
It's actions derive solely from itself. We can argue from that that how the universe is is derived entirely from how the infinite machine is and how the infinite machine is derives from itself.
We could look at how the universe emerged, certainly. However, you cannot examine how an infinite reality 'derives' from anything; it's infinite, it doesn't derive at all.
Since unconscious behaviour is chancey and potentially chaotic then without invoking intelligence and consciousness we can impute order, autonomy, self direction and control to our infinite machine.
No, you're still presuming an intent and a direction. There is simply a state, and the inevitable consequences of that state; that is not necessarily a matter of conscious or unconscious, it is 'aconscious' - a waterfall drops because gravitational effects distort space-time into a curve resulting in conserved momentum appearing to change the direction of water, but no-one needs to consciously or unconsciously process that requirement in order for it to happen, it happens independently of any consciousness.
