If visual {x} unlocks a ton of value you'd expect someone would have been doing visual math or visual novels by now and the market would eat it up. It may exist

If visual {x} unlocks a ton of value you'd expect someone would have been doing visual math or visual novels by now and the market would eat it up. It may exist but it didn't own the market for literature or science. Written word is still king. Not sure off hand what the advantage is but there does seem to be 'something' keeping writing on top of a visual centric approach across the board, not just in programming. Even on imgur where images are king the comments are mostly text.
