"How about just...temperature indicators? Most people with an industrial freezer probably want it set to a certain temperature, not just some value on an arbitrary and unknown scale."

"Probably because replicating natural human movement (or any natural movement, really) is incredibly difficult. We have hundreds of muscles interacting in a myriad of ways, and to replicate that motion with a few servos is no small feat. Not that robots aren't capable of realistic motion--Boston Dynamics' bots have shown significant improvement since their inception, and it shows--but it's a long road."

"I wonder what the weight rating for those hanging edges is. Sure, it can hold three grown men standing within the support structure, but what happens if someone sits on the corner? "

"If slipping is a concern, I would think the higher- friction pivot of your fingers would be more likely to cause it. That said, even if a completely free-spinning bearing does somehow cause issues, they could still include a cap with more friction. Having just a hole in the middle to rotate around feels like something is missing, as if the design isn't finished yet."

"Add a bearing and some caps and it's a fidget spinner. Plus, that way it's easier to roll. Somehow this feels both over- and under-designed, which is a shame given the price."
