I talked to someone about the extensibility of emacs, but the person I was speaking to assumed that any IDE is just as extensible by using Plug Ins.
Without turning the conversation into a university style lecture, what is one or two simple actions I can do in emacs to show someone what separates it from other IDES.
I mean, as a practical matter they are correct - most things people care about IDEs doing are just built in in other IDEs or doable via plugins. emacs is extremely niche and most people are correct to use something else.
It is an important skill to not care what other people use and not care what they think about what you use.
