Well, if they create a kind of visual builder that delivers similar results like Page Builder, Beaver Builder or Visual Composer... that could be quite interesting in terms of the content that regular users can create then.

I mean, while TinyMCE is nice and you can do many things with it... it is kind of limited and "traditional". This kind of editors was around back in the 2010 or earlier... and have not evolved a lot.

Of course, it will push the page builders even more "up", forcing them to be much more "rich" in features. Or so, to make them "different" and "unique".

In cases where you can't afford to have a page builder (whatever reason it may be), having Gutenberg do this might be really useful.

I hope that they eventually deliver. For me, this is a move in the right direction.
