PC. This is how they started, and that is, by and large, how they have remained. They have become prettier, more complex, larger, and aware of other PCs on a network; but their primary purpose is to enable the user to start or terminate a specific application (such as a word processor). Partly because of this rationale, controllers have been too much oriented to the workings of the PC and the application programs, and not enough to the relationship between the user and the PC. Tomorrow's controller will have to act as a mediator between the user and the various tasks and applications that are provided on the PC. To do this, it will have to be able to communicate both with the user, and the applications; it will also have to know more about both.
             To give a simple example - I use my PC most days, I have used it hundreds of times, but yet it doesn't even know my name! In fact, it knows absolutely nothing about me at all. Every time I come to use the PC, it comes as a complete surprise to it. It has no memory of me, of my habits, my working practices, my family, my friends or my interests. We are complete and utter strangers. I believe this has to change, and with the power of tomorrow's PCs, it will change.
             Another complaint I have about controllers is that they are far too passive, they are not proactive. If I do nothing, then my PC does nothing. Now I can, with some difficulty, arrange for various tasks to be carried out automatically without my being present, but this is only a beginning. Consider, I have to monitor the organisation and structuring of the files held on my PC. Why? I think the controller should do this for me, it knows about such things better than I do. It can get to know my requirements by observation, with confirmation by questioning me when necessary, and take care of it. Perhaps it could cogitate over such matters at night. While I get my rest, it can clear things up so they are refreshed in the morning. Let it...
