I like this picture:
I found it here. It is an escalator in the process of being replaced, at Charing Cross underground station, London. They’ve taken out the old one. They are now remaking whatever it is the new escalator will sit on top off. Then they will put in the new esacalator. It’s a routine they must have done dozens of times, with local variations to keep them on their toes. I do not doubt that when they finish their work, the escalator in question will function smoothly, no matter how many people ride on it or how heavy their luggage.
What I like about the photo is that it is, for me anyway, a reminder that there are still some things about our world that are progressing very nicely. The engineering of things like escalators continues to improve. But because the complexity that you see in this picture is, when the final object is rolled out, hidden, most people only think of such things on those rare occasions when they don’t work. At which point they grumble.
One of the big divisions in the world now, it seems to me, is between those who assume that such progress will necessarily continue, no matter how many mistakes the politicians make, and those who do not. Some people take technological progress for granted, while others notice it (often because they do it themselves for a living), want it very much to continue, but do not assume that it automatically will continue, no matter what.
