Emacs isn't dead

Emacs has been superseded by VSCode and IDEs.
IDEs have gotten good and we're now at a point where it's objectively a bad choice not to use Jetbrains/Visual Studio/XCode/RStudio.
As a driver of innovation Emacs is replaced by VSCode.
The support for avant garde languages such as D or Rust is better in VSCode.
New ideas get tried out in VSCode.

Web Apps are actually dead. Mobile apps won.

You don't notice, but many Mobile Apps are built with a web browser.
Aside from that Mobile Apps are done. People just use the 15 most popular ones.
Web Apps on the other hand are certainly not dead.
You're posting on one. Nobody uses BBSes anymore, textboards are way more convenient.
