Every instance of text needs to be dynamic. You can't just write "Text", you need to write "$text" (a variable) and have code that refers to a file containing that word in a given language to replace the variable with. It's tons of upkeep work, and you can never cover every single language known to man.
An icon on the other hand? "icon.svg". Done.
Ironically, in an effort to be global and inclusive we are throwing out all the languages and attempting to replace them with a single, universal iconography.
I fucking hate this trend, but I can understand and respect why it happens. People are fucking lazy and this is the course of least resistance overall.
