Robotic exoskeletons help Chinese tourists climb a punishing mountain

A couple of potential future uses I'm seeing here

- Military. If these exoskeletons can help tourists climb a punishing mountain, they could probably help soldiers do the same, carrying more gear than they'd normally be able to

- Humanoid robotics training data. Surely these things could collect tons of data about walking given they're attached to people's bodies. Could this be used to train an algorithm for an actual robot, without the human?
