There was an article on the MSN network recently that discussed technology that is being worked on right now.
The article gave predictions of how many years it would take before the general public would benefit from the various products.
It predicted that holo-technology will be available by 2016! Just 8 years from now.
The article did not mention replicators, but I'm sure that if that word is put into a search engine, you would find that someone is working on it.
