Don’t forget leap years! What’s 18.6 billion years between friends?
I’m sure they could make it go faster but I suspect the reason the robot works at this speed is the friction in the cube only raises the temperature a few degrees before the cube settles and can cool down. And pausing for 60 milliseconds so the human eye has time to register the cube positions probably doesn’t suffice.
You could probably get it down to a billion years without reducing it to just a blur. A couple million if you point a bunch of high speed cameras at it and show the last fifty moves on screens next to the machine. Or 30 machines all showing 1/30th of the cycle.
