Prediction: I believe eventually MS will kill Atom or let development languish. People will complain that "MS is evil" and "look who they were in the past" and so on, but devs will go where the features are. VS Code is one of the finest examples of open source Done Right™, and while it owes something to Atom and Electron, this is pure open source darwinism.
Can anyone who has stayed with Atom after evaluating VSCode comment on why to stay with Atom? I switched to VSCode and would never consider going back to Atom at this point. Since the GitHub acquisition, it makes no sense for MS to maintain both and I agree 100% with the parent comment that this will be killed soon.
Atom's find/replace interface was the favorite version of the feature I've used in any editor -- would be cool to see how that design evolved to support other kinds of automated edits (like refactorings).
