Everything is physical, and hence computation is physical. So
"[p]hysical, not computational" is a false dichotomy. And computation
does not require silicon, so this has nothing to do with whether
emotion is computable.

You yourself are evidence that computers can have emotions. You're a
computer, as am I. Chemicals and hormones have nothing to say against
this fundamental fact.
Most importantly, underlying all of this: In the theory of computing,
the theoretical properties of computers are addressed (including the
hypothetical 'hypercomputational' entities that have some advantage
over Universal Turing Machines). And nothing in physics has
demonstrated any capabilities beyond those specified by the theory of
computing, which is just the mathematical investigation of
abstractions over physical information-processing systems (and, at
times, fictional informational-processing systems). So don't believe
for a second that hearing about emotions being based on this or that
chemical process in any way implies they are not computable,
computational, or substrate independent. The first two are certain,
and the last is unknown but presumed due to both Occam's razor and the
historical lesson that whenever we consider ourselves "special"
without strong justification, physics comes around and smacks us down
for being so anthropocentrically biased.
