This is a really good business idea, it's going to be very successful. I also hate everything about it.

The selfie sticks were bad enough but just like you say soon every idiot tourist is going to have an autonomous drone following them wherever they go, capturing hours of social media material that no one's going to care about. Unless they catch you doing something that goes against their boring norms, because then they'll plaster it all over without a care for your privacy. I must have seen a dozen videos of "creepy old man naked in the woods near our children" or some similar phrasing when it turned out every time it was just some hippie nudist who thought he'd have a bit of peace and quiet being outdoors, far away from the city. But you can't go anywhere these days without these gopro morons filming your every move.

What makes you think this will be even remotely successful?

Because people love taking pictures and video clips of themselves and this makes it a lot easier to get shots from different angles. It's perfect for the self-obsessed crowd, for social media influencers, travel bloggers, etc. There is already a competitor and I'm sure future products are going to be improved in terms of sensing, autonomous flying and image quality. I'm not saying Snap is going to be market leader, just that such drones are going to sell.

Also autonomous flying has been in the works for other applications for years, now it's simply trickling down to the cheap consumer level where it can get sold to people who've never operated a quadcopter before and a going to buy this as a fun disposable gimmick.
