I appreciate that the question in the title may be a little bit vague. So far, my understanding of Gutenberg's longer term implications are:
i) WordPress will ultimately evolve into an entire front-end website assembly tool (similar to Wix).
ii) Blocks will will represent the core elements of future website assembly.
So my question is, what ultimately will be the impact on the concept of the WordPress loop? Are we likely to see Posts/Pages continuing as a kind of master block, with all other block types (what were previously widgets, shortcodes, advanced custom fields etc) then somehow embedded or tied to these master blocks (i.e. the WordPress loop?).
Or will, for example, each block type be associated with its own loop (e.g. called from the class loop with a new parameter specified within the traditional loop?).
I'm just struggling to understand the impact of Gutenberg on WordPress development over the short and medium terms.
The answer may be "no-one knows precisely at this point" but, then again, I suspect that there are already some indications about where this is going and if anyone is aware of what impact we can expect for developers, I would be keen to hear your thoughts.
