I have a existential question. Devs developing IDE's uses the same IDE to develop that IDE? I can't sleep thinking on that 🤔😂

I know it's not serious, but the answer is "sometimes".

I've written Netbeans plugins, and used Netbeans for it. From my understanding, many of the core Netbeans Devs certainly used to use Netbeans for Netbeans related Dev, once it'd passed a sensible stage.

However, I've also done work with BlueJ, and I certainly didn't use BlueJ for that.
