Personally, I expect to frequently accept and view documents from
otherwise untrusted, anonymous sources on the Internet.  I also expect
to distribute documents to others, as an anonymous untrusted source
myself, across the Internet.

I wouldn't argue against Postscript having many uses/benefits/strengths,
but the suggestion that it can fill all of the roles that PDF is used
for seems unfounded.
