While the author says that much of it can be attributed to the layers of software in between to make it more accessible to people, in my experience most cases are about people being lazy in their developing of applications.
For example, there was a case of how Claude Code uses React to figure out what to render in the terminal and that in itself causes latency and its devs lament how they have "only" 16.7 ms to achieve 60 FPS. On a terminal. That can do way more than that since its inception. Primeagen shows an example [0] of how even the most terminal change filled applications run much faster such that there is no need to diff anything, just display the new change!
