APL & descendants are array/vector (or matrix) languages.
Anyways, the majority of programmers like general purpose languages that are popular with other programmers, because that's how you get employed and make money. And what has happened in the last 20 years is that techniques from functional & vector languages have made their way into mainstream languages. Either in the syntax or in their libraries.
That's a good thing after the previous decade+ of "object orientation will solve all our problems" dogma.

Concatenative approaches remain relatively under-explored though.
