Only if you think of it as an "app", which often carries a connotation of singular or narrowly constrained purpose. I open an app to get directions, I open an app to see my email, I open an app to send a message, I open an app to check my grocery list.

Emacs isn't an app, it's a system. Is it also weird that we use the same systems (Linux, Windows, macOS) to code and organize our lives and to host a variety of limited purpose apps?
