The examples he gives aren't very clear. Let's just state one that's fairly obvious to me:
Back in the day, someone introduced tabs in browsers that made it possible to browse several websites in a single browser window. People loved it so much that they started running browsers with dozens of opened tabs. But then this caused more pain, because now people had too much tabs to navigate. And this sparked the creation of tab managers, which introduce more complexity in how people browse the web than they used to.
