While attending WordCamp US 2017, there were a number of sessions that stood out to me. Gutenberg and the WordPress of Tomorrow by Morten Rand-Hendriksen was one of them.
Hendriksen explains the state of WYSIWYG in WordPress and how it doesn't really exist but Gutenberg provides opportunities to change that. He explores developing sites without being confined to a small view port. He also performs a live demo of Gutenberg showing off its capabilities.
An interesting outcome from his presentation is the amount of optimism and excitement it generated from the audience. During the question and answer session, a member of the audience commented on how far Gutenberg has advanced in the last three months and that it looks cool to use now.
To gain insight into how Gutenberg can moonshot WordPress over its competition, watch Hendriksen's presentation.
