Stairs are a pretty underappreciated invention. Can you even imagine a world without them? How would we get to the second floor? Use a ladder?! No, no.
You’d think that with thousands of years of stairs existing, and the fact that everyone is fan, we would have a pretty good sense of how to make them by now. Turns out, no. What I don’t understand is who is making these terrible staircases? Have they never used stairs before? No. They probably use a ladder.
