I’d say that anecdote illustrates that human hands are not very good at the problem of Rubiks Cubing, if it is a reasonable task to assign in a single course. No matter how much speedcubers practice, they’re not going to be able to solve a cube in <0.4s. Looking at the slo-mo version, it seems like it might be able to go even faster, but it’s approaching the physical limits of the regular cubes not exploding… (WP tells me the human all-time record stands at >7x slower.) Even with unmodified cubes they’re still a lot faster (using Legos, of all things). Such high-speed robotics is a good example of why chaos doesn’t matter.
