Completely agree. Also: some people enjoy fiddling with their tools, installing extensions and configuring everything until it's just perfect. Other people (most, I would argue - the proverbial "silent majority") want to get something that works reliably "out of the box" and has most (not all, IntelliJ IDEs also have plugins of course) batteries included. They shockingly are even willing to pay money for this!

The dream is something batteries-included but still radically hackable. Emacs is slowly making this feasible via smaller and smaller "starter kits" as it adds new features. It's not perfect, and maybe this approach will never yield a fully productized solution like IntelliJ. But getting a full-featured Emacs setup hasn't meant building the world from scratch in a long time!
