But all 64-bit unixes support 32-bit applications! I am
including here Solaris, DEC-Unix, IRIX.

Yes, but the "process" very often involves deciding to run
applications in 32-bit mode. Indeed in many cases this makes
more sense, since many applications have absolutely nothing
to gain from 64-bit mode, and quite a bit to lose (increased
memory usage, which given cache behavior translates to
increased run-time).

Then you are definitely not quite up on things, given that
Linux most often is running on x86 machines which are 32-bits
by nature.

Will the ia-32 have disappeared 30 years from now? I would not
be so sure of the answer to this :-)

Well I hope that others are not taking this head-in-the-sand
viewpoint, or we may have another Y2K fiasco :-)
