Selecting a WordPress theme will become a UX (user experience) choice and largely irrelevant to the aesthetic (user interface or UI) choices. We developers will customize the visual aspects of our web properties with pre-built Gutenberg blocks, JavaScript code snippets, and custom CSS frameworks instead of what we think of today as themes. These visual artifacts are currently available as plugins – thereby making plugins as relevant to your site’s look-n-feel as any theme used to.
