Hi guys
& thanks for the feedback, Justin!
It feels great to be heard. A true Tavern! (I'm from Portugal and a taverna is a very special spot around here).
Best answers always have some love involved (thanks, Kel, for the concern :)

To be honest, I think I'm not that off. I've begun learning JS (and React) for some time, done some courses, I think I'm prepared for blocks and don't feel scared about the future. I think I'm just uncertain of a solid pathway. I believe I'm in search of the Holy Grail of WP right now - how to build a solid website.

Maybe this isn't the place to share long thoughts. I was preparing what was starting to be a huge response - that, and the fact I was on sick leave, justifies the off timing of this response. Sorry for that.

I don't want to delay this answer anymore, so, I think I'm going to arrange that huge thing I was writing and maybe "Ask the Bartender" in separate instances.

Just a quick one.. in ACF docs we have:
- "ACF blocks differ from WP blocks in that the data is decoupled from the design. This allows for faster development of blocks by focusing only on the HTML output."
- "Block data is saved within the “post_content” as an HTML comment. This makes them unique to metaboxes which save data to the “postmeta” table."
- "WordPress saves block data as HTML comments in the post_content. ACF blocks follow suit and save their data as a JSON object within that HTML comment."

Can't we think of ACF as a framework, like React, that solves things cleaner & more future proof?

Thanks &
See you all!
