Looks to be an amazing piece of engineering but seriously, what's the usecase? It looks to be targeted at the amateur market ('shoot like the pros') and I just don't see the demand or workability in this space.

To pick on a few hinted at on the page:

A game of football: Leaving a camera on a tripod on the sideline while I'm focused on the game? Not in any park I've ever played in. Taking the stick from my teammates for being enough of a nerd to set this up?

Skiing: Putting a camera on a tripod, unattended, on the piste? Then get the lift up to the top so you can ski back down towards the camera? Again, I can't see this ending well for the poor old camera.

Dirt biking/other extreme sports: because people often do these alone, and so need an automated cameraman to get any filming done?

EDIT: reading some of these comments my opinion has changed, there are more compelling use cases for this than I first thought of (like letting the person who would have done the filming relax and watch the event, whilst still attending to the camera, that's a great one). This is amazing tech but the main limiting factor for now is the risk of leaving such expensive equipment unattended. When the price falls I have no doubt this will be an extremely widely used tech, as widely used as cameras themselves are now.
