> First came the infamous infinite scroll. I remember feeling uneasy the first time a web page no longer had a bottom. Logically, I knew very well that everything a browser displays is a virtual construct. There is no physical page. It is just pixels pretending to be one. Still, my brain had learned to treat web pages as objects with a beginning and an end. The sudden disappearance of that end disturbed my sense of ease.

Your brain was wrong. And my fingers were hurting (and are hurting when I use websites without infinite scroll, like Hacker News).
