One of PGs essays hit on this when he talked about “blub”. Building a language for a specific solution/domain was/is expensive, but using a language to build abstractions or an internal domain specific language has been much more tractable. As such some languages are more or less suited for this activity; Lisp being the king then Ruby then etc. So to me the study languages was interesting from this DSL perspective.
