I've heard enough parables to know how this will play out, if it does happen: lots of dead bugs on the ground, bugs that will feed another species in the food chain. The lack of mosquito population and reproduction will starve species that depend on them. That change in the dynamic will ultimately be worse for ag production...

I'm all for reducing toxic chemicals from the food supply chain and this approach looks somewhat promising. Its just difficult to predict the consequences of even an ideal outcome. That isn't to say that we shouldn't try, but maybe we could work together to mitigate such effects before mass adoption, or reframe the problem such that lasers may not be needed in the first place.
