Communication is a means to an end, a tool, not an end in itself, or something with intrinsic/unassigned value. Why would we want more energy wasted on focusing on the packaging (or worse, how the packaging is made) by drawing attention to it, instead of helping directing it towards that which actually matters?

I largely agree with this, though I think:

1) there's some value in internally generated text (automatic documentation, autosummary) being less aggravating

2) there are assistive applications — speech generated from sign language and touch panel communication etc. — and those users deserve a tool that can communicate for them in a way that has controllable or even personalisable outcomes.

3) a process of de-sloppifying text might also help train thinking clarity.

In what sense will it be killed? I don't plan to stop writing my own messages or notes, just because AI can write, and I seriously doubt many other people who prefer their own voices will change either.
