Futurism

Soon (or, "soon") we will have computers without keyboards.  We will just talk.  Except those who cannot speak due to a speech impediment or muteness.  or deaf people.  Hmmm.  Maybe that's good news for carpal tunnel sufferers but not for others.
Soon (ibid) we will have everything imbedded with computerness and so you can touch the wall and it will tell you all about it's wallness.
Someday we will insert nanobots into our brains and speak fluent foreign languages.
Right now, I just want to know if I can catalog a cake pan with RDA, or with FRBR, or MARC or CCO or this new co-operative cataloging wiki.
No one seems to know the answer.
Here's another question: Why can't the Smithsonian, due to financial and technological constraints, catalog many of its realia collections?
