Well, Doc, you mentioned your afterlife view before, and I either
found it emotively, unpalatable (Damn. there's goes the human
amygdala again!) or found it too hard to comprehend, when you used
to say "read the universal dovetailer argument," (Darn that weak
cerebrum!), and so forth.
My own sense of things driven by both cranial structures, indicate
for me, that since there is and has been unending tragic goings on
in the world (perhaps 3.75 billion years worth?), so I in my
insight have decided its up to our species, and/or its descendents,
to sort thing out. I am believing that, lacking all other available
actions, computing is the way to go. the only way at this point.
99.95% of our species population thinks differently from I, and
taking that as a reasonable sign that I am on the wrong side of
things, once more, I persist anyway.
You look for and accept (as most do!) reality as it is. I sift
through science papers (like at ARXIV) and other popular online
source, attempting to look for possibilities of things, such as
cosmological registers of some sort, a MAC address in the sky, but
something, more read-write, a spacetime SSD, for a laugh.
I try to get some rationalist light (for a change) on afterlife,
soul, consciousness, meaning, etc. And I hope we can improve our
relations in general by extending our knowledge of that reality,
although with computationalism, we can never be sure our knowledge
*is* knowledge, except for a few first person indexical (like a
pain here&now or a pleasure here&now, that we can know but not
communicate rationally, nor justified).

I guess each one of us has his, or her, own motivation.
Mine is just to try to figure out what is reality, and what is the
relation between us and that reality.

I think most fundamental researchers are motivated by a curiosity
and fascination on some Reality that they are searching, and often,
it can happen they get cursed by the beauty of their theories,
which can help but can also become an handicap----that will depend
on many things.
So it is neither for the enjoyment of some science per se, nor for
helping humanity, it is by curiosity of what is real, with, in the
background some enjoyment for what we can see/conceive in the
process, and the idea that better knowing what is real can only
help humanity if she needs help.

I don't think this is the case. For example, in the theory of
statics,
used to construct bridges, solid objects with properties of tensile
strength, (mass) density, elasticity and so on are assumed, even
though ontologically, they are known to be composed of mostly empty
space, with those very ontological properties the result of
electromagnetic fields.
Most other physical models are the same - the example Brent gave of
using continuous fluid mechanics to predict hurricances is an
excelent point. Of course we know that the atmosphere is not a
continuum, but rather made up of a collection of molecules with
emergent properties that makes the continuous description a good one.
It may be that some physicists think that the objects of the Standard
Model (leptons, quarks, bosons etc) are somehow fundamental, but I
doubt
that many would stick to their guns on that.
But the Standard Model is used quite rarely for making predictions,
and is generally computationally infeasible. Classical dynamics is
much more widely used.
So I cannot see why someone pointing to the predictive power of
physics is in any way making an ontological statement of the form of
physicalism. IIRC, in the original context, Brent was trying to
tongue-in-cheek say that the laws of fluid dynamics is God, even
though I know he strongly asserts that God must be a person, so it
must have been some sort of satirical response. Nevertheless, I
didn't
see anywhere where he claimed that the models of physics were
ontological.
