Applying the phrase to an actual moving staircase seemed like the thing to do. Also, why don’t we call the down escalators ‘de-escalators’ or ‘descolators’? Same with elevators – both mean ‘to go up’ but we use the same name whether they’re going up or not. English makes no sense.
Also, PAX AUS 2015 just wrapped up and I had a ball. I was very lucky and got to try out virtual reality astronaut sim Earthlight on the HTC Vive and let me tell you this stuff is the real deal. I may have been in a noisy exhibition hall, but I was in SPACE, like Sandra Bullock in Gravity.
