Humans have expressed themselves in images long before they have expressed themselves in text.
Any system that forces humans to express themselves purely in ASCII, monospace, and monochrome is crude and borderline disrespectful towards human expression.
It made sense in 1983, when the technology to power these expressions was not prevalent. But why do this today? I know they exist, but who are the people who confine themselves this way? Is it acknowledged as an act of self-discipline or self-restraint? Some sort of an artistic statement? What is the process through which one arrives at "I will commit to this system, and always only communicate in written speech, laid out in uniform monochromatic typographic format. I will walk into these constraints voluntarily."
Any medieval monk writing manuscripts, any ancient Greek or Roman or Egyptian or Chinese capturing history and literature on parchments would have gasped at such a thought.
