The folks at MIT have taught their Cheetah robot how to jump over obstacles with no external support or safety harnesses.
The Cheetah robot is funded by DARPA, the Pentagon's advanced research program, and according to MIT this is the first robot that can run and jump over obstacles autonomously without direction from us obsolete humans.
The first of many, I assume. Before you know it, nowhere will be safe.
Full disclosure: I actually think this is amazing and I want one as a pet.
