Maybe, but if it ends up being  so then it's only because of the
marketing clout of basically one company (with support from all their
board-room friends, of course!  :-).

It would be interesting to see if the original inventors of PostScript
feel that PDFs should have a future or not....

Personally I find it almost impossible to champion any binary data
interchange format.  If you want efficient compression then pre-tune
your compression algorithm, but use it only as a fitler, not as an
integral part of the data interchange format!

Google could search most PS documents one heck of a lot easier than it
does PDFs.

BTW, there is no reason why PS couldn't be extended to support hypertext
and metadata.  PS' DSC are already a form of metadata.  Hypertext links
could be added to either PS or to the DSC.

I would have to question that interpretation of PDF's design goals....

Note also that PS is suitably flexible enough that one can build
real-time windowing systems with it too.
