The rapid evolution of Information Technology has meant the equally rapid expansion of Cyberspace. Tasks previously performed entirely by humans are now partially or fully computer controlled. Examples include expert systems (e.g. autopilots, medical systems and game-playing programs like Deep Blue), workplace software (e.g. spreadsheets, editors with spelling checkers, databases and graphics packages) and other applications software (e.g. email, search engines, hypertext, webbots and ecommerce). Important advances in Information Technology with direct impact on users have included the extension from isolated microprocessors to networks spanned by the web, the extension from batch processing to autonomous agents which even learn by modifying their behaviour in the light of their own 'experience', and the advance in interface design from punch cards to palm devices which adapt to the user's handwriting and to vocally-operated operating systems.
A foundation for Computer Ethics should not to require substantial alterations with changes in Information Technology: Information Ethics must be stable. For example, had it been developed thirty years ago, Information Ethics would have needed to have been robust against the advances mentioned in the previous paragraph.
