Don't be silly.  Asking if a program halts or not is not an error or a
bad question.  Asking if a context-free grammar is ambiguous or is not
an error or a bad question.  Asking if two groups are isomorphic or not
is not an error of a bad question.  You just say these things for the
sake of having an opinion.

The set of subsets of N is uncountable.  The set of Turing machines is
countable.  There must be an uncountable number of undecidable sets of
numbers.  That we've been able to find a few is handy, but it's not
surprising.
