Whether the challenge of mass producing cricket flour is actually worth solving of course, depends on demand for the product extending beyond novelty value, which is part of the problem with edible algae, also widely available in stores and rather simpler to produce and yet far from being a mainstream foodstuff.

As far as I'm aware use of cricket flour is also virtually nonexistent amongst the many cultures that consider whole insects a delicacy.

On the basis of both of the above I'd hazard that cricket flour is unlikely to become a significant staple food even if niche businesses perfect the art of cricket-farming.
