I think the concept is that people get lazy with voice-to-text and leave mistakes in.
I have been using some version of that for over a decade and it was never an issue in the past, so I am guessing many are getting around their hatred of writing by using tech do to the writing for them, without realizing it's also a lot of work to edit it afterwards!
I also think there's a big difference between using speech-to-text to get data into a word doc, then editing and pasting into a report, vs. using it to enter the text into a comments box on your phone or tablet.
