Late 1970s - Present: Fourth Generation Computers Following the invention of the first integrated circuits always more and more components could be fitted onto one chip. LSI (Large Scale Integration) was followed by VLSI (Very Large Scale Integration) and ULSI (Ultra-Large Scale Integration), which increased the number of components squeezed onto one chip into the millions and helped diminish the size as well as the price of computers. The new chips took the idea of the integrated circuit one step further as they allowed to manufacture one microprocessor which could then be programmed to meet any number of demands. Also, ensuing the introduction of the minicomputer in the mid 1970s by the early 1980s a market for personal computers (PC) was established. As computers had become easier to use and cheaper they were no longer mainly utilized in offices and manufacturing, but also by the average consumer. Therefore the number of personal computers in use more than doubled from 2 million in 1981 to 5.5 million in 1982. Ten years later, 65 million PCs were being used. Further developments included the creation of mobile computers (laptops and palmtops) and especially networking technology. While mainframes shared time with many terminals for many applications, networking allowed individual computers to form electronic co-operations. LANs (Local Area Network) permitted computers to share memory space, information, software and communicate with each other. Although already LANs could reach enormous proportions with the invention of the Internet an information and communication-network on a global basis was established for the first time.

Beautiful bodies However, artificial beings need not be invisible or look like Arnold Schwarzenegger in "Terminator". "My dream would be to create an artificial man that does not look like a robot but like a beautiful, graceful human being. The artificial man should be beautiful". Nadia Thalman's hopes for beautiful robots may become reality in the work of MIRALab, a research laboratory attached to the University of Geneva dedicated to realistic modelling of human functionalities. The laboratory has produced an artificial Marylyn Monroe showing just how beautiful artificial creatures can be, and there is a biography featuring details of her career and her - however virtual - love life. Yet beautiful creatures have been made before, at leas on the movie screen. Frank-N-furter, the protagonist of the Rocky Horror picture show ("I've been making a man / with blond hair and a tan / and he is good for relieving my /tension) did set remakrable esthetic standards. While in Hindu mythology, avatars are bodies chosen by gods for their representation on earth, often animals such as swans or horses, the avatars populating cyberspace have a different function. The cyber bodies of real people, often 3 dimensional images of creatures whose aesthetics reflects both the tastes prevalent in the entertainment and advertising industries as the state of art in visual representation.

Artificial intelligence approaches Looking for ways to create intelligent machines, the field of artificial intelligence (AI) has split into several different approaches based on the opinions about the most promising methods and theories. The two basic AI approaches are: bottom-up and top-down. The bottom-up theory suggests that the best way to achieve artificial intelligence is to build electronic replicas of the human brain's complex network of neurons (through neural networks and parallel computing) while the top-down approach attempts to mimic the brain's behavior with computer programs (for example expert systems).

Ross Perot Ross Perot, founder of EDS, is one of the richtest individuals of the US, and former presidential candidate of the Reform Party. A staunch patriot, Perot has been know for his aggressive business practices as well as for his close relationships to the military and other US governmental bodies. Perot reached 19 % in the 1992 presidential elections, but dropped to less than 10 % in 1996.
