Heh, I had a weird nightmare about that. I was typing on my laptop at a cafe, and someone came up to me and said, "Neat, you're going real old-school. I like it!" [because everyone had moved to AI voice transcription]
I was like, "But that's not a complete replacement, right? There are those times when you don't want to bother the people around you, or broadcast what you're writing."
And then there was a big reveal that AI had mastered lip-reading, so even in those cases, people would put their lips up to a camera and mouth out what they wanted to write.
