I can't make sense of that.  After all, the famous
"Eliza" program was according to this view a machine,
of course.  It was a specific program.  But it was
also what you, evidently, would call a natural
system because it was open to output from anyone.
No effort was made to "program in" every possible
response just as evolution makes no effort to 
"program in" to our DNA every possible contingency.

A TM which can be laid down on *any possible* tape
is analogous to a functioning robot that can be
presented with any possible environment in which
to struggle.  And just as the TM may fail to perform
in some wished-for way, so too the robot, like
ourselves, may simply be inadequate to its new
environment.  That's life.
