They (whoever they are) would be well-served to move to emacs, and stay there forever. I don't know which "antiquated" thing you're referring to, specifically, but it all works quite well. Both back in the day and today.
How often do you have emacs hanging because TRAMP is completing some network operation, for example? I’m a big emacs fan, have been using it since the 90s, and will likely never move away. But there’s no reason to pretend that it doesn’t have warts.
