I have a family member as an example . . . I can barely understand her on the phone (speaks to that missing 'reading comprehension and speech' requirement someone noted was missing from high school now) so I would not expect speech to text to work very well for her.
It is easy to get on a rant with this. STEM schools for example. They potentially turn out functional, employable, meat-machines who have never heard of Salvador Dali, Shakespeare, Hayden, governmental structures, or economic basics. If the power goes out and their batteries run dry they could have trouble making something to eat let alone carrying on with higher level functions.
This is not new. There have been people like this through out time Immemorial. Some of my coworkers from my generation were occasionally nothing more than a seat warmer who could do some of the basic functions of the job. Then there were those who would just leave it for the next guy to finish or make it go away with a pencil, aka pencil whipped it.
Then there are those who are good at some things but not others.
