Ha, I remember this religious debate all the way back in the days of text-mode word processing in the 80s on CP/M and PC. I was indoctrinated in the WordStar camp where style controls were visible in the editor between actual text characters, so you could move the cursor between them and easily decide to insert text inside or outside the styled region. This will forever seem a more coherent editing UI to me.
This might be why I also liked LaTeX. The markup itself is semantic and meant to help me understand what I am editing. It isn't just some keyboard-shortcut to inject a styling command. It is part of the document structure.

Only for the 3 primitive styles that were supported? 3 table cells of RedBold GreenLowerCaps BlueUnderlineItalic isn't easy anymore
But also - there wasn't a single app in the 80s with a different easy approach, right? So removing noise had a downside.
> styling command. It is part of the document structure.
Not for the most used markdown markers, where styling = semantic.
Same, same.
And... I preferred WordPerfect's separate "reveal codes" pane, which reduced the opportunity for ambiguity. WP 5.1 has never been equalled as a general-purpose word processor.
