The programmer or the computer? The programmer, of course.
Yeah, but who cares about the computer? What is important however is the user
. How long do you want to wait for a website to bring up its home page? How much stuttering do you accept from the movie player? How slow can a plane respond to a command from its pilot?
So, we need languages with big speed of development.
The majority of the users doesn't care one iota in which language the application is written in. And even the computer savvy don't really care for the majority of the applications they use in what language it's written. But they don't want to wait too long.
