One function of R&D involves how to manufacture things cheaply, quickly + en masse.
Those efficiencies that started with consumer drones now serve drones used in war. DJI being used at the start of the war is the evidence of that.
Continuation of that investment in R&D will also lead to new technologies: such as quieter drones, drones that can carry more, go further, and be controlled through difficult to counter means.
It's blithely short sighted to think that the technology is already at its maximum, or that these concepts are disconnected from each other. It's a type of naive thinking that people on the internet do to rationalise a false sense of security.
Also: to address another set of comments in this thread - China aren't looking at EUV so they can break into the graphics cards market or lower the price of RAM. Absolute utter numpties.
