Yes. I am interested in what machines (and other entities) can prove 
about themselves.
And also about what is true about themselves, but that those 
machines/entitities cannot prove, but can deliver as true in a way or 
another.
The propositional parts of those discourse has been captured by the 
modal logical systems G and G* respectively (Solovay 1976).

I use "computer" for universal machine. "Ordinateur" in french. All 
loebian machines I talk about are universal machine. All universal 
machine "believing" in classical tautologies and in the laws of 
addition and multiplication, and in some induction formulas is lobian.

In Belgium, in France and in other countries, I'm afraid, among most 
scientists, I mean.
I rule out also "metaphysics" because I don't know what it means. 
Historically it concerns the books which were on the sides of the books 
on physics in the texts by Aristotle (but is this a legend?).
In "metaphysics", "meta" has not the same sense that "meta" in computer 
sciences and mathematical logics. Create confusions.

Sure. Look: digital machine metaphysics is a branch of metamathematics!

I don't even really believe in any precise frontiers between all those 
things. It is useful only for the curriculum vitae and for searching 
job and getting social profile, but any fundamental questioning is up 
to eventually move frontiers or suppress some.
