>Programming languages are really just vehicles to supply abstractions to programmers. People think of programming languages as being good or bad for a given purpose, but they are really criticizing the abstractions that a language embodies. The progress in programming languages has been incredibly slow because new programming languages are difficult to create and even more difficult to get adopted. When you have a new programming language, the users have to rewrite their legacy code and change their skills to accommodate the language. So, basically, new programming languages can come about only when there is an independent revolution that justifies the waste of the legacy, such as Unix which gave rise to C, or the Web which gave rise to Java. Yet it's not the languages that are of value, but only the abstractions that the languages carry.
