Mom and Dad are just about to arrive at the airport here. In order to meet them, I just arrived at the airport too. I took the train which has its last stop at the terminal.
Except… there’s a brand new terminal (new last week!) and now the train stops there instead of at the old terminal. So when the train arrived I stumbled off with quite a few other baffled passengers and we all ricocheted around the giant empty building trying to figure out how to reach familiar ground.
The new terminal is vast and shiny. So much so that your tiny monitor can’t possibly convey it properly.
And, this escalator holds still when no one is on it — and then detects when people climb on and starts moving!
This presents a classic example of iterative design. If an escalator is stopped, no one can tell if it’s an ‘up’ or a ‘down’ escalator. When I approached one from the wrong direction, it buzzed to alert me of my mistake. Sooner or later they’ll be running the place.
