I hope this claim will not be exploited to postpone or abandon actions towards mitigation of the climate catastrophe.

Among scientists and on slrpnk - no surprise. But the society is sadly not concerned enough. I feel no one does a fuck.

That's right, but still each electrically powered UAV trip seems to be better to air quality and CO_2 emissions than a trip by a combustion-engine-powered car.

people want to do them

Not necessarily. I think many people, including me, are perfectly happy spending whole day at home. It is very convenient when you can order something almost to your door, and it would be ideal without burning fossil fuels or exploiting delivery people.

Yep, this is sadly a physical problem in the essence, not created virtually by capitalist economy. The negative price is just how the capitalist economy reacts at it.

Obviously not.

This is not obvious at all.

The better question would be why do you think it could?

For example, by reduction of traffic jams – unless you believe that this can be achieved by that most people will abandon their cars in favor of public means of transport, but sadly, hoping that is quite naive. UAVs could deliver parcels so many people would not need to sit in a diesel car to go shopping.

That's very true. I think that such articles are important anyway to remind wider audience about the problem.

By making easier and cheaper to deliver products as grocery and catering services, not only Amazon / Alibaba / the like parcels. And people going shopping / restaurant make a significant part of the traffic.
