There are more useful systems developed in languages deemed awful than in languages praised for being beautiful — many more. - Bjarne Stroustrup

The connection between the language in which we think/program and the problems and solutions we can imagine is very close. For this reason restricting language features with the intent of eliminating programmer errors is at best dangerous.

"Legacy code" is a term often used derogatorily to characterize code that is written in a language or style that (1) the speaker/writer consider outdated and/or (2) is competing with something sold/promoted by the speaker/writer. "Legacy code" often differs from its suggested alternative by actually working and scaling.

There are only two kinds of languages: the ones people complain about and the ones nobody uses.
