So, a half remembered Radiolab episode or maybe it was 99% Invisible talked about this. If I remember rightly they did consider changing it because it was so much quicker and easier typing in English which matters in the digital age. Until someone figured they could break down all the Chinese characters into a much smaller selection of base shapes. So you could make a character by pressing a small selection of keys. So it meant a much more manageable keyboard. I think it’s even resulted in the fastest Chinese typist being faster than English.
