I thought it was most interesting because it shows an automated mechanical sensing device that exploits a common lock. Many other types of locks can be picked by a human using sensory feedback and some basic techniques. It seems like not too big a jump to see this kind of device being built for other locks and even a more general purpose device being built for a wide range of locks.
Metasploit for devices. With drones, ascenders and brute force, physical security is dead. Anything too tedious for a human will be done by a robot. Witness the touch screen robots that can unlock numeric passwords on smart phones.
