No comment. :-)

But, but... How can *QM* be the ultimate framework? -- it doesn't
include gravity (GR).

Are you sure about that? ;-)

Leaving aside the determinate-indeterminate question, a case could be
(iconoclastically) made that the observer-observable "paradigm" was
*excluded* not *included* by GR and QM. You might say that GR and QM
take the "observer" *out* of the picture. In GR you could say that the
observer is transformed away -- it's all relative, and all that.
Likewise, in QM it seems that a robot taking measurements is
sufficient to "collapse the wave function." Of course, you could also
argue that robots are people, too. ;-)
The current work by physicists in all this is to find a way to
*combine* both QM and GR into a unified theory which works at all
scales and matter-energy densities.
And then, what's all this dark matter and dark energy stuff?... ;-)
To slightly paraphrase Richard Feynman, no one even understands
*quantum mechanics*. :-)

Ultimately, many things may not be knowable in principle. How can
"all" be knowable to humans who are part of the very "system" being
considered, i.e., the cosmos? :-)
