A lot of these technologies are being developed and its pretty awesome. However, I'll argue there's clearly space for a keyboard in the virtual world.
If you want to sculpt a model in the real world, you'd use clay and your hands. We can use VR to move away from KBM interaction for things like that.
If you want to write a book in the real world you...type it out. Its the best way we know to get text out of your brain and somewhere else. Don't throw the baby out with the bathwater.
Indeed everything in its place. However I really don't think I would go into a virtual world to write a book, or do any other kind of activity that requires a lot of keyboard interaction.
I used to hope for the unlimited monitor space, now I am not so sure how practical that really is.
