Human languages are usually the result of hundreds and thousands of years of complex influences, random changes, and adaptations. Even artificial languages such as Esperanto betray their origins in real language. High-level computer languages are, however, more deliberate conceptions. The challenge of inventing a programming language is quite appealing to some people because the language defines how a person conveys instructions to the computer. It was estimated in 1993 that there had been over 1000 high-level languages invented and implemented since the beginning of the 1950s.
