Essentially, this sounds like temporal sampling bias. The points about ease of recombination and augmentation bespeak a lack of infrastructure investment in post-text meda, not a fundamental property. Yes, communication mediums begin with text. But the low emotional bandwidth (and low availability of presence in real-time interactions) concretely limits the kinds of transmissions that can be made.
Your writing, however, does raise a spectacular question.
How can we increase the bandwidth of text across the machine/​brain barrier?
