What Does Speed Have to do with it?

“Interpreted languages are slow” is a common myth. Interpreted languages provide an increase in development speed but trade it off for a decrease in runtime performance. In other words, interpreted languages love developers and hate end-users.

None of those beliefs is meaningful. It isn’t that they are true or false, it’s that they are incoherent. Languages are not running a footrace. They aren’t charging down a linear track together, all doing the same thing.

We use different languages for very different things.
