In reply to Lamont.

@Andre: Not really, afaik. There is a Gutenberg module which was presented at Drupal Europe, but Drupal isn't about to ditch CKEditor or anything - the big push at the moment is the layout_builder module - which is designed kind of as a core replacement for paragraphs and panels, and later a refreshed admin theme and eventually, a React based admin UI (javascript initiative).

(Hope that helps.)
