Well in this list we follow the option "2". (As its name indicates).
To progress we need to make the everything idea more precise. Most  
naive "everything idea" are either trivial and non informative, or can  
be shown inconsistent.
QM is an amazing everything theory, astoundingly accurate. Yet it is  
based on comp (or variety of comp), which means that if you take  
serioulsy the first person experiences into consideration, then you  
have to derive the Schroedinger waves from a deeper purely  
arithmetical derivation.
But with the computable, something happens: the discovery of the  
universal machine (accepting Church's thesis).
This makes enough to confront all universal machine, actually the  
Löbian one will even understand why", with a "consciousness/reality"  
problem, or first-person/third person relation problem, and that the  
Löbian machine can develop the means to explore the many gaps which  
exists there.

I think we have made progress. We "know" (assuming digital mechanism)  
that we know nothing about the consequence of addition and  
multiplication, but that we can explore, and that it is divided into  
sharable and non sharable parts.

We may correct a widespread error: the sharable part is the objective  
and doubtable part, the non sharable part is the subjective and  
undoubtable part.

We have a theology. A "greek" one, by which I mean, that is the bad  
news for some, we have to do mathematics.

And nobody ask you to believe it, unless you decide to say "yes" to  
some doctor and believe that 2 + 2 = 4.

You can call it a toy theology, given that it is the theology of an  
ideally relatively self-referentially correct Löbian machine. It  
exists as a branch of math, and it applies to us if comp is true and  
as far as we are correct ourselves, which we can never known. But we  
can bet on levels, like "nature" apparently already did, and prey or  
hope or something like that.

The quest of truth will continue. If comp is true reality is beyond  
fictions. For the best or the worth, this depends *partially* on us.  
Who "us"? "Us" the universal machines.

The motto: be vigilant toward any *form* of authoritative argument,  
even those of nature. Eventually it is a matter of personal freedom,  
but it is far better to get the personal understanding in those  
matter. All universal machine  "soon or later" understands this.
