I also see more and more systems going to UCS and using the
semantics defied on UCS, and further definitions on UCS such as
conversion and sorting. But I do not see this as eliminating POSIX,
I see POSIX and UCS as a perfect match and POSIX can be used to promote
UCS and definitions on UCS to other systems not using UCS. And I believe
that systems not running UCS will be around for a long time to come.

Well, I see POSIX systems as the heart of the Internet now, and
actually also as the birthplace of Internet. And I believe POSIX
will stay as a very significant part of the Internet, certainly
upgrated to support UCS.
I see POSIX and UCS as complimentary, not antagonistic.
