PC-based Control, Software and Bus TrendsMIT. It allowed users to type in phrases such as “Open the door.” Dungeonwould react and describe what happened after the door wasopened.Other programs such as Lotus Notes can interpret a wide range ofnatural-language commands. Lotus Notes allows you to type phrases like“Schedule a meeting for next Monday at 9:00 with Engineering development.”The program will make the proper entry in your calendar with thecorrect contacts. These types of applications appear to understand whatyou tell them as long as it is related to mail, calendar and contacts.Natural-language interfaces are a sign that software is gettingsmarter and becoming more human. The speed capabilities of computerswas illustrated in Deep Blue’s 1997 victory over chess world championGarry Kasparov. Deep Blue is a powerful 32-node IBM RS/6000 SP computerand was able to calculate hundreds of millions of positions per secondto decide on the optimal move. Kasparov only could examine a fewpositions per second.The processing power that lets Deep Blue simulate millions of possiblechess outcomes is being used to perform time-consuming tasks suchas the simulation of weather patterns and other complex physical models.Computer software is also beginning to use human-like pattern recognitionwhich is typically referred to as neural net techniques. Neuralnets learn from experiences. In the future computers will aid doctors inanalyzing a patient’s condition and assist them in creating new drugsright in the office.Future of PC SoftwareFuture personal computer software will probably replace the virtualdesktop in Windows with the Webtop. You may soon use Windows occasionally,but living in a Web browser as the Webtop takes over from thedesktop.In the near future you will plug into the Webtop wherever you go. Itwill know who you are, what applications you use, and how you wantyour interface to look. No more configuring of your personal computerfor communications will be needed. Communications will be easier, aseveryone logs into one big network. The software industry needs tochange fundamentally in the same way the microchip changed the designof circuits.©2001 by The Fairmont Press, Inc. All rights reserved.
