42. To send email, you put a document on someone else's stream. To add a note to your calendar, you put a document in the future of your own stream. To continue work on an old document, put a copy at the head of your stream. Sending email, updating the calendar, opening a document are three instances of the same operation (put a document on a stream). Sounds like a gap in Unix's file metaphor. Would it be reasonable to copy a file to /proc/mail/coworker@company.com/ and have the right thing happen? 57. Nowadays we use a scanner to transfer a document's electronic image into a computer. Soon, the scanner will become a Cybersphere port of entry, an all-purpose in-box. Put any object in the in-box and the system develops an accurate 3D physical transcription, and drops the transcription into the cool dark well of cyberspace. So the Cybersphere starts to take on just a hint of the textural richness of real life. I think mobile phone cameras will be the "scanner" here.
