I loved every bit of Matt's talk until he mentioned of phase 2-3-4 of Gutenberg where it seems like WordPress developers, theme and plugin devs while get sidelined as we have the ability to do almost everything within WordPress. (headers, menus, widgets, wide-layouts etc) which has actually been the cake for these guys.

As a WP-Designer, i'm totally okay with the progress but not the whole community.

Matt and team, good work and I really appreciate every bit but kindly think through this.
Peace :)
