Not into selfies. But for a travel photographer/videographer, drones are a great! Personally, i'd go for the DJI spark or Mavic over this.
A computer is like a bicycle for the mind.
These things are already banned mostly everywhere. Annoying sound, annoying invasion of public space and privacy. This is the equivalent of listening to music throught your phone's speakers in public.
It's not literally a Fun Fact, but I like it and I'll probably use it when a situation presents itself calling forth for some simple, witty response, e.g. to those who opine, I don't like or use computers. Never have; never will.
T'anks!
