Good question.
There seems to be strong lobbying for insects as human food, in particular from companies that would be happy feed us with their own shit as long as it's cheap and they could get away with it
The green-left seems to enjoy that idea. Exactly why is hard to tell - especially on HN, but let's say I don't think it's rational.
So I guess, successful lobbying?

You don't need left there, there is no green right
The why is not that hard to understand - insects provide a lot of proteins compared to how much food they consume over their lifetime.
But yes, the obvious place to start is to use it for feeding chickens and not humans. Why chickens? Because insects are part of their natural diet when they are free. There is just a bunch of infrastructure problems that need to be solved for that to work as insects have pretty different problems to solve compared to other parts of the food production chain.
