The worst is when I see someone using vim or Emacs over SSH. If you think Electron apps are bad, imagine adding a network round trip between every keystroke!
That, plus the ability to rejoin a session even from a different IP, makes working over SSH doable even from airplane Wi-Fi.
Terminal Emacs over ssh is, well, just like anything else in a terminal over ssh. Can't say I notice the latency unless the datacenter is on the other side of the country.
