Reminds me of the mosquito laser. It would target only female mosquitos of the specific breed (they are the malaria carriers). It was only prototyped and never commercially produced.

Indeed. These are often predictable outcomes when there is lack in economy of scale or scope.

I saw a video where this company is doing exactly that for weeds:

Great idea, I hope it works.

For weeds, this is already a thing. There are weed bots that kill with fire and others that kill with lasers.
