No, the nature of identity and cognition can be already described with
sufficient precision. It's just empirically threads about personal identity
are fueled by sentiments similiar to now obsolete ones: those about phlogiston,
vis vitalis and creationism. These, too, have gone round in circles for
decades and centuries, leading pretty much nowhere.

Statements "I believe that first-person introspective view is special"
and "I'm convinced cognition is not a physical process described by
known physical laws or require deep quantum magic", "continuity matters"
"location is part of system identity", "atoms themselves, not their
spatiotemporal arrangement constitute identity" are such sterile arguments.
Ultimatively, they cannot be refuted by means other than a direct
demonstration, preferrably from a first-person perspective (but even
then, some observers will still remain unconvinced, claiming the
zombie clause, or trying to get the experimenter persecuted for their

Absolutely. Apparently, too counter-intuitive for some people to accept,
despite based on solid seat-of-the-pants science and empirically refuted
by daily routine in IT.

Of course they're illuminating. But have they convinced many? It doesn't seem
