The technology is interesting. The small size and cheapness combined with AI-style automation could provide a cost-effective solution to surveying and monitoring all kinds of live processes.
However the reliance on direct line of sight lasers seems limiting even if this is a technological advance. Eventually it is likely to replaced by self-powered drones.
The use of mechanical insects in general also worries me. There is a potential impact on biological ecosystems if birds eat mechanical insects or spend energy chasing them. Efforts to ensure such drones are readily distinguishable from real insects should be encouraged.
