Genetic algorithms and the like are still useful for various combinatorial search problems. Not everything can be mapped to a smooth function, and so there will always be (in my opinion at least) room for metaheuristics.

Well put.

I seem to remember encountering some work in ML parameter selection (which can be simplified to a combinatorial problem), which made use of metaheuristics. Having trouble recalling the group who was working on it right now, though.
