> I’ve become convinced that “little languages”—small languages designed to solve very specific problems—are the future of programming,

Yes, but over time very specific problems become bigger/different problems which the little language isn't ideal for, the original developers move on leaving someone new to figure out the problem and language which is probably poorly documented and very brittle. Application developers probably aren't suited to writing and maintaining language code.

The only caveat is an external system provided with its own language - like RDB/SQL - which is proven and well maintained - but its hard to call SQL a little language.
