I think there is an interesting debate to have here: (1) Why would this happen, (2) Why should this happen (if one thinks it should)?, (3) Should this happen (if one thinks that it will happen)? I think we have for sure seen it happen with texting, with the adoption of emojis and abbreviations, but it remains to be seen if this will happen with voice. Of all the interfaces, nothing comes anywhere close to its primordial, deeply-embedded-in-our-DNA status. All other interfaces were invented, including text (almost 1 Billion adults on this earth are not literate), and so are malleable to refinement and fine tuning, because they were invented. Voice is not an invention. And so, it may be the case that we won’t see the same happen with it.
Someone who solidly stands on your side of the debate, is Bruce Ballentine, who wrote book — if you have not read it already— titled, “It’s better to be a good machine than a bad person”: https://www.amazon.com/Better-Good-Machine-Than-Person/dp/1932558098
It was written 10 years ago, before the arrival of voice automation outside of telephony and dictation. I’m going to go re-visit that book, in our new context.
