I remember MySpace and Facebook were having a nice marketshare for a long time, as long as Firefox, Windows and the rest. Now that TikTok surpsases Instagram, I am sure it is critical time for WordPress to implement Gutenberg right. If I was responsible I would ensure it serves the general public a consistent experience by aligning the design of WP dashboard, Gutenberg & Full Site editor to have one design language. Find a way for the WP.org repository to allow paid themes and plugins and handle payments as in-app purchases and subscriptions. Also simplify the whole management of the open source project which is a terrible mess. Hear my word, sooner or later something faster, better, running on JamStack would come up and tons of people would jump the ship. Be warned!
