I’d like to see a better analysis, that’s all. I don’t know either way, and I’d bet that the co2 of the drone show is orders of magnitude lower than fireworks, for example. But as with lots of emerging technologies, it’s hard to make direct comparisons - is the lithium going to be recycled at end of life, did it come from “good” mines, how much of the plastic will end up in landfill and how much is pla/plant-based, and how does all this compare to the cardboard and explosive in the fireworks. Also, do the electronics contain conflict minerals, and are they recyclable, and what’s the expected life of the drones? How do the chemicals for colour in the fireworks affect their pollution, and how are they produced? Having recently seen an fairly damming look at Formula E (run on generators that are flown from England to wherever the races are, that kind of thing), I’m just intrigued to know more about how the sausage is made, if you see what I mean. It’s in our interest to ask this kind of thing, in the same way that it would have paid to ask more questions about how single-use plastics would be disposed of, rather than just trusting that them using less trees in their construction was worth it. These things never have a simple answer, and I’d like to know as much as possible
