In reply to Sunni.

There is a mega trend as a pattern, as in web design, fashion, cinema and whatever creative business: Some once very creative design starts to get trendy and is admired. It's hard, and not easy to copy and bring in just the tweaks you need for your brand. Then some tool makes it faster and easier, with no skill, no coding, to make exactly what "all" wants. Some day all look the same, in a way. Things start over, and the creative ones are again in front.

WordPress itself has never been a design tool. I think it will never be. It's a content management system. The themes and builders, extensions are, more or less design tools, fixed design or something in between.

Now, themes may be less relevant, and block patterns may be more relevant. It may, as theme frameworks and page builders always has, make it easier for the layman to create designs that before was advanced. It should no be seen as a threat. Before WordPress the layman had a hard time publishing content in a descent way at all, in whatever design.

Some put all too much in the React driven nature of the block editor, or the similar javascript driven nature of page builders. I do a lot with both page builders and the block editor, making my own components (blocks) without touching javascript. You can still use PHP/HTML to create. It's their behaviour in the editor hey belong that depend on scripting.

I', not a designer, but I have created so much content and structure focused things with tools like Block Lab (+HTML/PHP) that I know a designer, skilled in HTML/CSS can create just anything, as they can when making a theme template. Plus, it will be visually rendered in the editor. Reusable beyond a specific theme, if I want.

Web design, with or without WordPress as backend, need professional designers more than ever. As it was 10 or 20 years before. And they need to be even better and and to adapt to current technology. And I do not mean React. But with some understanding of it, and and Javascript in general, make templates/blocks behave more interestingly when used in the corresponding editor, and may be on the front.

The world tend to be more streamlined, effective in doing things hat have become trivial. Everything hat comes as part of a change may be seen as threat. The thing is to look beyond. That's the duty of the professional.

What is it that makes you feel you can not "do your thing inside WP" any more?
