I agree, especially about the ground crews—it would seem logical that you would want people nearest to the source you are trying to measure, given that they would need to carry heavy equipment. About the drones in general, yeah, there are a lot of drones around. The only thing I look forward to with drones is the erosion of centralized food suppliers—who own all the shelf space and thus can fix market entry. Now anyone with a warehouse or website can enter with a delivery system. You could get farmers, maybe one day, just delivering their own milk if they are five miles from the target—or just tanking their milk to a warehouse fifty miles away or whatever, because now they are getting better deals.

The problem here in New Zealand is that the farmers all joined a centralized conduit to the supermarkets, which drove up prices so they made more—but also drove them up for everyone. There are other farmers who wanted to be independent, but they just did not have a way in unless they joined the conduit. Now, hopefully, they do. If I could order raw milk and have it here, I would be drinking that instead of the watered-down milk on the shelf—which seems like 5% milk to me. Although these days, I don't drink normal milk at all.

About the spies, I agree. However I think they are all spies, I think in reality - all the politicians, in every county are compromised and just spies. The only thing they have in common, is they don't work on behalf of the people that elected them. There are of course, many examples of this. Also, on another note - New Zealand had an "alleged" Chinese spy as a member of parliament (who used to train spies "allegedly" ) - this might seem strange, but its actually the way things are done these days - that is why the power costs so much in new zealand - and everything - they are trying to price the people out of the property market so black rock etc., can buy it all https://www.news.com.au/national/former-chinese-spy-trainer-and-nz-mp-faces-calls-to-be-sacked/video/5c1f9ce89c9e5403f7cf7e3a4c109b20
