Yeah, right -- who am I kidding?
Anyway, after thinking about what was really required for these things to be possible, it occurred to me that these people are describing absolutely fantastic machines. What they describe is not necessarily intuitive, and most of the time has to do with telepathy (which is coming, but it's taking it's sweet time), but every now and then something truly interesting pops out.
One gentleman apparently got the idea that to send email, you wrote a letter on paper, balled it up, and inserted it into an orifice on the system. And the system, being the magnificent piece of technology it is, would just figure out how to turn that into data, locate the recipient, and produce email on their end.
Now, if that were possible, it'd be a hell of a thing. It's not, though, so it becomes a joke.
I'm going to keep reading, though. I keep getting good ideas for new gadgets in my stories.
