In 1987 Apple Computer produced a concept video for a hypothetical product called the Knowledge Navigator.
Having a normal conversation with your computer as though you were conversing with a friend seems to be the most paleo-futuristic aspect of this video. The inefficiency of such a system certainly raises questions about the user interfaces of tomorrow.
(Inefficiency aside, there's no doubt that I'd make my virtual butler wear a bowtie too.)
