The scale being used won't matter. For instance, take music. It went from records, to DVDs, to memory on ipods, to small downloads, later to larger downloads. Today, it is much easier to listen to a given song. For computers storage is a factor, memory is a factor. I was amazed at the progress in screen sizes - video cards keeping up with the amount of pixels that need to be pushed. So, they will hit size limits, but then you will see themes like the already unfolding transputer concept. I think we will carry our profiles around and just plug them into computer stations, or plug into a computing network (like the internet, but where we share cpu cycles). The progress needed is in software integration. And in concepts, and in privacy controls (and the flip side - access controls). -- sorry for the rambling.
