Thanks for sharing this, but is a comedy skit from almost two decades ago - or any time period - really a valid method of debunking potential scientific progress made within that same time period? It reminds me of when people post SNL skits as proof of why [insert person inaccurately being made fun of either in a biased or exaggerated manner for the purpose of humor] is Actually A Bad Person. I mean yeah, the technology at face value is hilarious to think about, and goofy, but so are a lot of things that actually work pretty well.
I’m curious why you think mm accuracy and non-foe detection would be terribly difficult in 2021. Going off your example, I’m pretty sure a mosquito would appear rather different to any detection system than a human, or in the case of a field, a bee or something like that.
